GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(172, 340) = 14620
GCD(172, 340) = ( 172 x 340 ) / 14620
= 172 / 340
= 172
Step2:
LCM(4, 958) = 1916
GCD(4, 958) = ( 4 x 958 ) / 1916
= 4 / 958
= 4
Step3:
LCM(2, 129) = 258
GCD(2, 129) = ( 2 x 129 ) / 258
= 2 / 129
= 2
So, Greatest Common Divisor of 172, 340, 958, 129 is 1
