Given numbers are 642, 710, 577, 757
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 710) = 227910
GCD(642, 710) = ( 642 x 710 ) / 227910
= 642 / 710
= 642
Step2:
LCM(2, 577) = 1154
GCD(2, 577) = ( 2 x 577 ) / 1154
= 2 / 577
= 2
Step3:
LCM(1, 757) = 757
GCD(1, 757) = ( 1 x 757 ) / 757
= 1 / 757
= 1
So, Greatest Common Divisor of 642, 710, 577, 757 is 1
