GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(147, 421) = 61887
GCD(147, 421) = ( 147 x 421 ) / 61887
= 147 / 421
= 147
Step2:
LCM(1, 996) = 996
GCD(1, 996) = ( 1 x 996 ) / 996
= 1 / 996
= 1
Step3:
LCM(1, 555) = 555
GCD(1, 555) = ( 1 x 555 ) / 555
= 1 / 555
= 1
So, Greatest Common Divisor of 147, 421, 996, 555 is 1
