Given numbers are 198, 921, 124, 917
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(198, 921) = 60786
GCD(198, 921) = ( 198 x 921 ) / 60786
= 198 / 921
= 198
Step2:
LCM(3, 124) = 372
GCD(3, 124) = ( 3 x 124 ) / 372
= 3 / 124
= 3
Step3:
LCM(1, 917) = 917
GCD(1, 917) = ( 1 x 917 ) / 917
= 1 / 917
= 1
So, Greatest Common Divisor of 198, 921, 124, 917 is 1
