You need at least two numbers to find a GCF.
Factors of 575: 1, 5, 23, 25, 115, 575Factors of 23: 1, 23GCF (575, 23) = 23
The Greatest Common Divisor of 575, 1890 and 10 is 5.
575 115,5 23,5,5
575 115,5 23,5,5
Use a factor tree. 575 115,5 23,5,5 5 x 5 x 23 = 575
The factors of 575 are:1, 5, 23, 25, 115, 575The factors of 4972 are:1, 2, 4, 11, 22, 44, 113, 226, 452, 1243, 2486, 4972The Greatest Common Factor (GCF) is:1
The GCF of 9, 15, and 75 is 3.9 = 3 x 315 = 3 x 575 = 5 x 5 x 3GCF = 3
The greatest common factor of 30 and 75 is 15.Method 1: Listing FactorsList all the factors of both numbers and the highest factor that is the same is the greatest common factor.Factors of 30: 1, 2, 3, 5, 6, 10, 15Factors of 75: 1, 3, 5, 15, 25The greatest common factor is 15.Method 2: Prime FactorizationFind the prime factorization of each number. The prime numbers that the numbers all share multiply to the great common factor.30=2*3*575=3*5*53*5=1530 and 75 share one 3 and one 5. Therefore, the greatest common factor is 15.
lowest common multiple of 25 and 115 is 575.
The GCF of 25, 60, and 75 is 5.The factors of 25 are: 1, 5, 25The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60The factors of 75 are: 1, 3, 5, 15, 25, 75The common factors are: 1, 5The Greatest Common Factor (GCF) is: 5
575 is the LCM of 23 and 25
