GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 946) = 73788
GCD(156, 946) = ( 156 x 946 ) / 73788
= 156 / 946
= 156
Step2:
LCM(2, 851) = 1702
GCD(2, 851) = ( 2 x 851 ) / 1702
= 2 / 851
= 2
Step3:
LCM(1, 989) = 989
GCD(1, 989) = ( 1 x 989 ) / 989
= 1 / 989
= 1
So, Greatest Common Divisor of 156, 946, 851, 989 is 1
