Given numbers are 981, 195, 634, 783
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 195) = 63765
GCD(981, 195) = ( 981 x 195 ) / 63765
= 981 / 195
= 981
Step2:
LCM(3, 634) = 1902
GCD(3, 634) = ( 3 x 634 ) / 1902
= 3 / 634
= 3
Step3:
LCM(1, 783) = 783
GCD(1, 783) = ( 1 x 783 ) / 783
= 1 / 783
= 1
So, Greatest Common Divisor of 981, 195, 634, 783 is 1
