GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(147, 956) = 140532
GCD(147, 956) = ( 147 x 956 ) / 140532
= 147 / 956
= 147
Step2:
LCM(1, 871) = 871
GCD(1, 871) = ( 1 x 871 ) / 871
= 1 / 871
= 1
Step3:
LCM(1, 641) = 641
GCD(1, 641) = ( 1 x 641 ) / 641
= 1 / 641
= 1
So, Greatest Common Divisor of 147, 956, 871, 641 is 1
