Given numbers are 520, 480, 394, 631
The list of prime factors of all numbers are
Prime factors of 520 are 2 x 2 x 2 x 5 x 13
Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5
Prime factors of 394 are 2 x 197
Prime factors of 631 are 631
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 520, 480, 394, 631
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(520, 480) = 6240
GCD(520, 480) = ( 520 x 480 ) / 6240
= 520 / 480
= 520
Step2:
LCM(40, 394) = 7880
GCD(40, 394) = ( 40 x 394 ) / 7880
= 40 / 394
= 40
Step3:
LCM(2, 631) = 1262
GCD(2, 631) = ( 2 x 631 ) / 1262
= 2 / 631
= 2
So, Greatest Common Divisor of 520, 480, 394, 631 is 1
