Complete step-by-step answer: LCM can be expressed as the product of highest power of each factor involved in the numbers. In other words No, two numbers can’t have 15 as their HCF and 175 as LCM because HCF of the numbers must be a factor of the LCM. Since 15 is not a factor of 175, it is not possible.

Can two numbers have 18?
Answer Expert Verified No, two numbers can’t have 18 as their HCF and 380 as LCM because HCF of the numbers must be a factor of the LCM. Since 18 is not a factor of 380, it is not possible.

How to find the GCF of 15 and 21?
Frequently Asked Questions on GCF of 15 and 21 1 Find the prime factorization of 15 15 = 3 x 5 2 Find the prime factorization of 21 21 = 3 x 7 3 Multiply those factors both numbers have in common in steps i) or ii) above to find the gcf: GCF = 3 4 Therefore, the greatest common factor of 15 and 21 is 3
Which is the greatest factor of two numbers?
The GCF or the greatest common factor of two or more numbers is the greatest factor among all the common factors of the given numbers, whereas the LCM or the least common multiple of two or more numbers is the smallest number among all common multiples of the given numbers.
How do you calculate the greatest common factor?
Given two whole numbers, subtract the smaller number from the larger number and note the result. Repeat the process subtracting the smaller number from the result until the result is smaller than the original small number. Use the original small number as the new larger number. Subtract the result from Step 2 from the new larger number.
