Given numbers are 530, 480, 642, 844

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

Apply this formula for all numbers.

Step1:

LCM(530, 480) = 25440

GCD(530, 480) = ( 530 x 480 ) / 25440

= 530 / 480

= 530

Step2:

LCM(10, 642) = 3210

GCD(10, 642) = ( 10 x 642 ) / 3210

= 10 / 642

= 10

Step3:

LCM(2, 844) = 844

GCD(2, 844) = ( 2 x 844 ) / 844

= 2 / 844

= 2

So, Greatest Common Divisor of 530, 480, 642, 844 is 2
