Given numbers are 390, 280, 962, 520

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

Apply this formula for all numbers.

Step1:

LCM(390, 280) = 10920

GCD(390, 280) = ( 390 x 280 ) / 10920

= 390 / 280

= 390

Step2:

LCM(10, 962) = 4810

GCD(10, 962) = ( 10 x 962 ) / 4810

= 10 / 962

= 10

Step3:

LCM(2, 520) = 520

GCD(2, 520) = ( 2 x 520 ) / 520

= 2 / 520

= 2

So, Greatest Common Divisor of 390, 280, 962, 520 is 2
