2 x 3 x 5 = 30
3 x 5 x 5 = 75
3 x 5 = 15, the GCF.
Prime factorization of 32 = 2x2x2x2x2 Prime factorization of 90 = 2x3x3x5 Prime factorization of 30 = 2x3x5 What is common in the prime factorization of the numbers? Only 2 is common, so GCF is 2.
The GCF of 15, 25, and 30 is 5.The prime factorization of 15 is 3*5.The prime factorization of 25 is 5*5The prime factorization of 30 is 2*3*5So the GCF of 15, 25, and 30 is 5.
The GCF of 30 and 55 is 5.The prime factorization of 30 is 2*3*5.The prime factorization of 55 is 5*11Therefore, the GCF of 30 and 55 is 5.
the GCF of 9 & 30 = 3 Prime Factorization of: 9 = 3 * 3 30=.....3 * 2 * 5 =========== GCF = 3
It is: 60
Prime factorization of: 30 = 2 x 3 x 5 44 = 2 x..........2 x 11 ================ GCF=2
2 x 3 x 5 = 303 x 3 x 3 x 5 = 1353 x 5 = 15, the GCF
Take 30/42, for example. The prime factorization of the numerator (30) is 2 x 3 x 5. The prime factorization of the denominator (42) is 2 x 3 x 7. This will help you find the GCF or the LCM.
The tree finds the prime factorization. The prime factorization finds the GCF. Example: 30 and 42. 30 15,2 5,3,2 42 21,2 7,3,2 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the common factors. 2 x 3 = 6, the GCF
Example: 30 and 42 Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the factors in common. 2 x 3 = 6, the GCF
*)1 5)5 3)15 2)30 The prime factorization of 30 is 2 x 3 x 5.
The LCM of 25 and 30 is: 150The prime factorization of 25 = 5x5The prime factorization of 30 = 2x3x5GCF = 5But, what is the use of calculating GCF here?Answer: If we divide the product of 25 and 30 by GCF then the result is LCM.Product of 25 & 30 = 25x30 = 750So, LCM = 750/5 =150Least Common Multiple (LCM) for 25 30 is 150
