GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(458, 403) = 184574
GCD(458, 403) = ( 458 x 403 ) / 184574
= 458 / 403
= 458
Step2:
LCM(1, 832) = 832
GCD(1, 832) = ( 1 x 832 ) / 832
= 1 / 832
= 1
Step3:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
So, Greatest Common Divisor of 458, 403, 832, 642 is 1
