Given numbers are 345, 639, 202, 977

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

Apply this formula for all numbers.

Step1:

LCM(345, 639) = 73485

GCD(345, 639) = ( 345 x 639 ) / 73485

= 345 / 639

= 345

Step2:

LCM(3, 202) = 606

GCD(3, 202) = ( 3 x 202 ) / 606

= 3 / 202

= 3

Step3:

LCM(1, 977) = 977

GCD(1, 977) = ( 1 x 977 ) / 977

= 1 / 977

= 1

So, Greatest Common Divisor of 345, 639, 202, 977 is 1
