Given numbers are 520, 784, 72, 549

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

Apply this formula for all numbers.

Step1:

LCM(520, 784) = 50960

GCD(520, 784) = ( 520 x 784 ) / 50960

= 520 / 784

= 520

Step2:

LCM(8, 72) = 72

GCD(8, 72) = ( 8 x 72 ) / 72

= 8 / 72

= 8

Step3:

LCM(8, 549) = 4392

GCD(8, 549) = ( 8 x 549 ) / 4392

= 8 / 549

= 8

So, Greatest Common Divisor of 520, 784, 72, 549 is 1
