GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(147, 342) = 16758
GCD(147, 342) = ( 147 x 342 ) / 16758
= 147 / 342
= 147
Step2:
LCM(3, 981) = 981
GCD(3, 981) = ( 3 x 981 ) / 981
= 3 / 981
= 3
Step3:
LCM(3, 142) = 426
GCD(3, 142) = ( 3 x 142 ) / 426
= 3 / 142
= 3
So, Greatest Common Divisor of 147, 342, 981, 142 is 1
