It is 105 bacause 3*5*7 = 105
3 x 5 = 15 3 x 7 = 21 3 x 5 x 7 = 105, the LCM
3 x 5 = 15 2 x 3 x 5 = 30 2 x 3 x 5 = 30, the LCM
12=22x3 15=3x5 So the LCM of 2, 12 and 15 is 22x3x5 = 60
The LCM of the given numbers is the product of all different prime factors to their greatest power. If there are no exponents, the greatest power of the prime factors is 1 and each different prime factor is used in the multiplication:prime factors of 15 are 3 x 5;prime factors of 21 are 3 x 7;the LCM of 15 and 21 is 3 x 5 x 7 = 105
3 x 5 = 15 No exponents required.
Two or more numbers are normally needed to find the LCM
3 x 5 = 15 3 x 7 = 21 3 x 5 x 7 = 105, the LCM
3 x 5 = 15 2 x 3 x 5 = 30 2 x 3 x 5 = 30, the LCM
No prime power exists since there are no duplicate prime numbers in the prime factorization.
12=22x3 15=3x5 So the LCM of 2, 12 and 15 is 22x3x5 = 60
No prime power exists since there are no duplicate prime numbers in the prime factorization.
3 x 5 = 15 3 x 7 = 21 Combine the factors, eliminating duplicates. 3 x 5 x 7 = 105, the LCM
prime factorization of each: 2x3 , 3x5, 2x2x5 so LCM = 2x2x3x5 = 60
Prime factorization of 15 = 3x5Prime factorization of 50 = 2x5x5Prime factorization of 75 = 3x5x5LCM = 5x5x3x2 = 150
3 3 x 5 Since 15 is a multiple of 3, it is automatically the LCM.
The LCM of the given numbers is the product of all different prime factors to their greatest power. If there are no exponents, the greatest power of the prime factors is 1 and each different prime factor is used in the multiplication:prime factors of 15 are 3 x 5;prime factors of 21 are 3 x 7;the LCM of 15 and 21 is 3 x 5 x 7 = 105
Prime Factorization of 9 and 15The prime factorization of 9 is:3 X 3The prime factorization of 15 is:3 X 5
