Given numbers are 574, 530, 764, 639

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

Apply this formula for all numbers.

Step1:

LCM(574, 530) = 152110

GCD(574, 530) = ( 574 x 530 ) / 152110

= 574 / 530

= 574

Step2:

LCM(2, 764) = 764

GCD(2, 764) = ( 2 x 764 ) / 764

= 2 / 764

= 2

Step3:

LCM(2, 639) = 1278

GCD(2, 639) = ( 2 x 639 ) / 1278

= 2 / 639

= 2

So, Greatest Common Divisor of 574, 530, 764, 639 is 1
