GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(637, 981) = 624897
GCD(637, 981) = ( 637 x 981 ) / 624897
= 637 / 981
= 637
Step2:
LCM(1, 167) = 167
GCD(1, 167) = ( 1 x 167 ) / 167
= 1 / 167
= 1
Step3:
LCM(1, 549) = 549
GCD(1, 549) = ( 1 x 549 ) / 549
= 1 / 549
= 1
So, Greatest Common Divisor of 637, 981, 167, 549 is 1
