How to calculate the LCM of 91 and 98?
To make things easier, start with larger factors of the number, and keep breaking them down to the primes: Take the highest count of each prime number. There are two 7s in 98, but only one 7 in 91, so take two 7s, 2 and 13. Multiply these together: 7 x 7 x 2 x 13 = 1274. Therefore, the LCM of 91 and 98 is 1274.
Which is the least common multiple in this calculator?
Calculator Use The Least Common Multiple (LCM) is also referred to as the Lowest Common Multiple (LCM) and Least Common Divisor (LCD). For two integers a and b, denoted LCM (a,b), the LCM is the smallest positive integer that is evenly divisible by both a and b. For example, LCM (2,3) = 6 and LCM (6,10) = 30.
What is the greatest common factor of 91 and 98?
There are two 7s in 98, but only one 7 in 91, so take two 7s, 2 and 13. Multiply these together: 7 x 7 x 2 x 13 = 1274. Therefore, the LCM of 91 and 98 is 1274. Consider this question: What is the greatest common factor of 84 and 144?
