GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 912) = 298224
GCD(981, 912) = ( 981 x 912 ) / 298224
= 981 / 912
= 981
Step2:
LCM(3, 845) = 2535
GCD(3, 845) = ( 3 x 845 ) / 2535
= 3 / 845
= 3
Step3:
LCM(1, 456) = 456
GCD(1, 456) = ( 1 x 456 ) / 456
= 1 / 456
= 1
So, Greatest Common Divisor of 981, 912, 845, 456 is 1
