Given numbers are 436, 758, 619, 639

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

Apply this formula for all numbers.

Step1:

LCM(436, 758) = 165244

GCD(436, 758) = ( 436 x 758 ) / 165244

= 436 / 758

= 436

Step2:

LCM(2, 619) = 1238

GCD(2, 619) = ( 2 x 619 ) / 1238

= 2 / 619

= 2

Step3:

LCM(1, 639) = 639

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

= 1 / 639

= 1

So, Greatest Common Divisor of 436, 758, 619, 639 is 1
