Given numbers are 658, 386, 843, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(658, 386) = 126994
GCD(658, 386) = ( 658 x 386 ) / 126994
= 658 / 386
= 658
Step2:
LCM(2, 843) = 1686
GCD(2, 843) = ( 2 x 843 ) / 1686
= 2 / 843
= 2
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 658, 386, 843, 921 is 1
