Given numbers are 458, 109, 840, 628
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(458, 109) = 49922
GCD(458, 109) = ( 458 x 109 ) / 49922
= 458 / 109
= 458
Step2:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
Step3:
LCM(1, 628) = 628
GCD(1, 628) = ( 1 x 628 ) / 628
= 1 / 628
= 1
So, Greatest Common Divisor of 458, 109, 840, 628 is 1
