Given numbers are 639, 402, 837, 847

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

Apply this formula for all numbers.

Step1:

LCM(639, 402) = 85626

GCD(639, 402) = ( 639 x 402 ) / 85626

= 639 / 402

= 639

Step2:

LCM(3, 837) = 837

GCD(3, 837) = ( 3 x 837 ) / 837

= 3 / 837

= 3

Step3:

LCM(3, 847) = 2541

GCD(3, 847) = ( 3 x 847 ) / 2541

= 3 / 847

= 3

So, Greatest Common Divisor of 639, 402, 837, 847 is 1
