Given numbers are 102, 180, 989, 748
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(102, 180) = 3060
GCD(102, 180) = ( 102 x 180 ) / 3060
= 102 / 180
= 102
Step2:
LCM(6, 989) = 5934
GCD(6, 989) = ( 6 x 989 ) / 5934
= 6 / 989
= 6
Step3:
LCM(1, 748) = 748
GCD(1, 748) = ( 1 x 748 ) / 748
= 1 / 748
= 1
So, Greatest Common Divisor of 102, 180, 989, 748 is 1
