Given numbers are 458, 167, 642, 415
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(458, 167) = 76486
GCD(458, 167) = ( 458 x 167 ) / 76486
= 458 / 167
= 458
Step2:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
Step3:
LCM(1, 415) = 415
GCD(1, 415) = ( 1 x 415 ) / 415
= 1 / 415
= 1
So, Greatest Common Divisor of 458, 167, 642, 415 is 1
