Given numbers are 635, 470, 550, 645

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

Apply this formula for all numbers.

Step1:

LCM(635, 470) = 59690

GCD(635, 470) = ( 635 x 470 ) / 59690

= 635 / 470

= 635

Step2:

LCM(5, 550) = 550

GCD(5, 550) = ( 5 x 550 ) / 550

= 5 / 550

= 5

Step3:

LCM(5, 645) = 645

GCD(5, 645) = ( 5 x 645 ) / 645

= 5 / 645

= 5

So, Greatest Common Divisor of 635, 470, 550, 645 is 5
