Given numbers are 458, 642, 379, 742
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(458, 642) = 147018
GCD(458, 642) = ( 458 x 642 ) / 147018
= 458 / 642
= 458
Step2:
LCM(2, 379) = 758
GCD(2, 379) = ( 2 x 379 ) / 758
= 2 / 379
= 2
Step3:
LCM(1, 742) = 742
GCD(1, 742) = ( 1 x 742 ) / 742
= 1 / 742
= 1
So, Greatest Common Divisor of 458, 642, 379, 742 is 1
