Given numbers are 458, 680, 947, 684
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(458, 680) = 155720
GCD(458, 680) = ( 458 x 680 ) / 155720
= 458 / 680
= 458
Step2:
LCM(2, 947) = 1894
GCD(2, 947) = ( 2 x 947 ) / 1894
= 2 / 947
= 2
Step3:
LCM(1, 684) = 684
GCD(1, 684) = ( 1 x 684 ) / 684
= 1 / 684
= 1
So, Greatest Common Divisor of 458, 680, 947, 684 is 1
