Given numbers are 981, 638, 809, 922
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 638) = 625878
GCD(981, 638) = ( 981 x 638 ) / 625878
= 981 / 638
= 981
Step2:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
Step3:
LCM(1, 922) = 922
GCD(1, 922) = ( 1 x 922 ) / 922
= 1 / 922
= 1
So, Greatest Common Divisor of 981, 638, 809, 922 is 1
