Given numbers are 756, 639, 968, 838

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(756, 639) = 53676

GCD(756, 639) = ( 756 x 639 ) / 53676

= 756 / 639

= 756

Step2:

LCM(9, 968) = 8712

GCD(9, 968) = ( 9 x 968 ) / 8712

= 9 / 968

= 9

Step3:

LCM(1, 838) = 838

GCD(1, 838) = ( 1 x 838 ) / 838

= 1 / 838

= 1

So, Greatest Common Divisor of 756, 639, 968, 838 is 1
