Given numbers are 128, 577, 645, 617
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(128, 577) = 73856
GCD(128, 577) = ( 128 x 577 ) / 73856
= 128 / 577
= 128
Step2:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
Step3:
LCM(1, 617) = 617
GCD(1, 617) = ( 1 x 617 ) / 617
= 1 / 617
= 1
So, Greatest Common Divisor of 128, 577, 645, 617 is 1
