Given numbers are 780, 462, 70, 530

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

Apply this formula for all numbers.

Step1:

LCM(780, 462) = 60060

GCD(780, 462) = ( 780 x 462 ) / 60060

= 780 / 462

= 780

Step2:

LCM(6, 70) = 210

GCD(6, 70) = ( 6 x 70 ) / 210

= 6 / 70

= 6

Step3:

LCM(2, 530) = 530

GCD(2, 530) = ( 2 x 530 ) / 530

= 2 / 530

= 2

So, Greatest Common Divisor of 780, 462, 70, 530 is 2
