Given numbers are 438, 656, 837, 159

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

Apply this formula for all numbers.

Step1:

LCM(438, 656) = 143664

GCD(438, 656) = ( 438 x 656 ) / 143664

= 438 / 656

= 438

Step2:

LCM(2, 837) = 1674

GCD(2, 837) = ( 2 x 837 ) / 1674

= 2 / 837

= 2

Step3:

LCM(1, 159) = 159

GCD(1, 159) = ( 1 x 159 ) / 159

= 1 / 159

= 1

So, Greatest Common Divisor of 438, 656, 837, 159 is 1
