Given numbers are 208, 161, 458, 634
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(208, 161) = 33488
GCD(208, 161) = ( 208 x 161 ) / 33488
= 208 / 161
= 208
Step2:
LCM(1, 458) = 458
GCD(1, 458) = ( 1 x 458 ) / 458
= 1 / 458
= 1
Step3:
LCM(1, 634) = 634
GCD(1, 634) = ( 1 x 634 ) / 634
= 1 / 634
= 1
So, Greatest Common Divisor of 208, 161, 458, 634 is 1
