GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(818, 637) = 521066
GCD(818, 637) = ( 818 x 637 ) / 521066
= 818 / 637
= 818
Step2:
LCM(1, 172) = 172
GCD(1, 172) = ( 1 x 172 ) / 172
= 1 / 172
= 1
Step3:
LCM(1, 492) = 492
GCD(1, 492) = ( 1 x 492 ) / 492
= 1 / 492
= 1
So, Greatest Common Divisor of 818, 637, 172, 492 is 1
