The list of prime factors of all numbers are
Prime factors of 650 are 2 x 5 x 5 x 13
Prime factors of 665 are 5 x 7 x 19
Prime factors of 287 are 7 x 41
Prime factors of 381 are 3 x 127
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 650, 665, 287, 381
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(650, 665) = 86450
GCD(650, 665) = ( 650 x 665 ) / 86450
= 650 / 665
= 650
Step2:
LCM(5, 287) = 1435
GCD(5, 287) = ( 5 x 287 ) / 1435
= 5 / 287
= 5
Step3:
LCM(1, 381) = 381
GCD(1, 381) = ( 1 x 381 ) / 381
= 1 / 381
= 1
So, Greatest Common Divisor of 650, 665, 287, 381 is 1
