The GCF is 5. Method: Because 3045 is such a large number, find the prime factors of 50 and check whether any of them divide into 3045. The prime factors of 50 are 2, 5, and 5. 3045 ÷ 5 = 609, which is not divisible by another 5, since it does not end in 5 or 0. Nor is it divisible by 2, since it is not an even number. Therefore, the greatest common factor of 50 and 3045 is 5. (3045 = 3 x 5 x 7 x 29)
6090
An example should illustrate the process. Find the common factor of 38 and 14. Dividing 38 by 14 gives a remainder of 10. Repeat with the smaller two numbers. 14 divide by 10 gives a remainder of 4. 10 divided by 4 gives a remainder of 2. 4 divided by 2 gives a remainder of 0. The last non-zero number is the greatest common factor. In this case, 2.
Do you mean greatest common divisor? You must start by factoring both numbers: 580 = 2*290 = 2*10*29 = 2*2*5*29 (29 is prime) 609 = 3*203 = 3*7*29 Note that 29 is common, but there are no other shared factors So the answer is 29.
Factors of 4263: 1, 3, 7, 21, 29, 49, 87, 147, 203, 609, 1421, 4263 Factors of 126: 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126 GCF (4263, 126) = 21
609 = 609/1
The common factors of 609 and 957 are 1, 3, 29 and 87. No 3-digit numbers.
