The LCM of 3 and 21 is 21
The Least Common Multiple (LCM) for 3 21 is 21.
To find the Least Common Multiple (LCM) of 7, 3, and 21, we first need to identify the prime factors of each number. The prime factors of 7 are 7, of 3 are 3, and of 21 are 3 and 7. Then, we take the highest power of each prime factor that appears in any of the numbers. In this case, the LCM of 7, 3, and 21 is 21, as it includes the highest power of both 7 and 3.
LCM OF 9,3 AND 21 IS 63. CHECK FOR YOURSELF IF YOU ARE NOT SURE.
3 3*7=21 3*30=90 * * * * * That is the Greatest Common Factor, GCF, not the LCM. LCM(21, 90) = 630
