Given numbers are 938, 626, 129, 647
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(938, 626) = 293594
GCD(938, 626) = ( 938 x 626 ) / 293594
= 938 / 626
= 938
Step2:
LCM(2, 129) = 258
GCD(2, 129) = ( 2 x 129 ) / 258
= 2 / 129
= 2
Step3:
LCM(1, 647) = 647
GCD(1, 647) = ( 1 x 647 ) / 647
= 1 / 647
= 1
So, Greatest Common Divisor of 938, 626, 129, 647 is 1
