Given numbers are 495, 237, 145, 639

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

Apply this formula for all numbers.

Step1:

LCM(495, 237) = 39105

GCD(495, 237) = ( 495 x 237 ) / 39105

= 495 / 237

= 495

Step2:

LCM(3, 145) = 435

GCD(3, 145) = ( 3 x 145 ) / 435

= 3 / 145

= 3

Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 495, 237, 145, 639 is 1
