Given numbers are 639, 270, 695, 513

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

Apply this formula for all numbers.

Step1:

LCM(639, 270) = 19170

GCD(639, 270) = ( 639 x 270 ) / 19170

= 639 / 270

= 639

Step2:

LCM(9, 695) = 6255

GCD(9, 695) = ( 9 x 695 ) / 6255

= 9 / 695

= 9

Step3:

LCM(1, 513) = 513

GCD(1, 513) = ( 1 x 513 ) / 513

= 1 / 513

= 1

So, Greatest Common Divisor of 639, 270, 695, 513 is 1
