Given numbers are 240, 715, 163, 644
The list of prime factors of all numbers are
Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5
Prime factors of 715 are 5 x 11 x 13
Prime factors of 163 are 163
Prime factors of 644 are 2 x 2 x 7 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 240, 715, 163, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(240, 715) = 34320
GCD(240, 715) = ( 240 x 715 ) / 34320
= 240 / 715
= 240
Step2:
LCM(5, 163) = 815
GCD(5, 163) = ( 5 x 163 ) / 815
= 5 / 163
= 5
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 240, 715, 163, 644 is 1
