45 (9*5 and 15*3)

factoring9=3*310=2*512=2*2*315=3*5LCM=2*2*3*3*5=180The LCM of 9, 10, 12, and 15 is 180.

The LCM of 3, 5, 9, and 15 is 45.

45 is the LCM of 15, 9 and 5.

First break the numbers down into their prime factors:9 = 3215 = 3 x 55 = 5The LCM is the product of all the primes in each list. However if the number occurs in list twice it is only counted once.So LCM of 9, 15 and 5 = 3 x 3 x 5 = 45An example: studymaths.co.uk/keytopics/hcfandlcm.htmllcm(5, 9, 15) = 45.5 = 59 = 3^215 = 3 x 5lcm = 3^2 x 5 = 4545

The LCM is 45.

The LCM of 3 and 5 is 15. The multiples of 3 are , 6, 9, 12, 15, and so on. The multiples of 5 are 5, 10, 15, and so on. The LCM is 15.

The LCM of 5, 9, and 15 is 45.

The LCM of 15 9 and 3, would be 45

The multiples of 3 are: 3, 6, 9, 12, 15, 18 etc ...The multiples of 5 are: 5, 10, 15, 20, etc ...The multiples of 15 are: 15, 30, 45, etc ...The lowest common multiple of 3, 5, and 15 is 15, so the LCM = 15

lcm(6, 12, 9, 15) = 180 6 = 2 x 3 12 = 2^2 x 3 9 = 3^2 15 = 3 x 5 lcm = 2^2 x 3^2 x 5 = 180

45 factoring 15=3*5 9=3*3 45=3*3*5 lcm=3*3*5

35 is not the LCM of 3 and 5, 15 is. LCM means Lowest Common Factor. To find the LCM of 3 and 15 you have to list the multiples: 3, 6, 9, 12, 15, 18, 21 etc. 5, 10, 15, 20, 25, etc. The LCM is the least common number in both the lists, which is 15.

The Least Common Multiple (LCM) of 3, 9, and 15 is 45.

Factor them. 3 x 3 = 9 3 x 5 = 15 Combine the factors, eliminating duplicates. 3 x 3 x 5 = 45, the LCM

The LCM is 45.

LCM of 9 15 and 21 is 315. Prime Factorization: 9 = 3 x 3 15 = 3 x .......5 21 = 3 x ............7 35 =.............5 x 7 ============ LCM=3 x 3 x 5 x 7 = 315

90. 5 = 5 9 = 32 15 = 3 x 5 18 = 2 x 32 lcm = 2 x 32 x 5 = 90

The LCM of (9,15) is 3. 9 = 3 * 3 15 = 5 * 3 therefore 3 is a common multiple. also three is the lowest multiple. therefore... LCM (3,15) = 3

3 x 3 = 9 3 x 5 = 15 The GCF is 3. 3 x 3 x 5 = 45, the LCM

The LCM is 90.

The LCM is: 45
