Given numbers are 948, 129, 69, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(948, 129) = 40764
GCD(948, 129) = ( 948 x 129 ) / 40764
= 948 / 129
= 948
Step2:
LCM(3, 69) = 69
GCD(3, 69) = ( 3 x 69 ) / 69
= 3 / 69
= 3
Step3:
LCM(3, 643) = 1929
GCD(3, 643) = ( 3 x 643 ) / 1929
= 3 / 643
= 3
So, Greatest Common Divisor of 948, 129, 69, 643 is 1
