Prime factors of 407 are 11 x 37
Prime factors of 675 are 3 x 3 x 3 x 5 x 5
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 915, 620, 407, 675
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(915, 620) = 113460
GCD(915, 620) = ( 915 x 620 ) / 113460
= 915 / 620
= 915
Step2:
LCM(5, 407) = 2035
GCD(5, 407) = ( 5 x 407 ) / 2035
= 5 / 407
= 5
Step3:
LCM(1, 675) = 675
GCD(1, 675) = ( 1 x 675 ) / 675
= 1 / 675
= 1
So, Greatest Common Divisor of 915, 620, 407, 675 is 1
