GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(162, 321) = 17334
GCD(162, 321) = ( 162 x 321 ) / 17334
= 162 / 321
= 162
Step2:
LCM(3, 958) = 2874
GCD(3, 958) = ( 3 x 958 ) / 2874
= 3 / 958
= 3
Step3:
LCM(1, 972) = 972
GCD(1, 972) = ( 1 x 972 ) / 972
= 1 / 972
= 1
So, Greatest Common Divisor of 162, 321, 958, 972 is 1
