Given numbers are 130, 474, 780

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

Apply this formula for all numbers.

Step1:

LCM(130, 474) = 30810

GCD(130, 474) = ( 130 x 474 ) / 30810

= 130 / 474

= 130

Step2:

LCM(2, 780) = 780

GCD(2, 780) = ( 2 x 780 ) / 780

= 2 / 780

= 2

So, Greatest Common Divisor of 130, 474, 780 is 2
