Given numbers are 390, 968, 546, 947

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

Apply this formula for all numbers.

Step1:

LCM(390, 968) = 188760

GCD(390, 968) = ( 390 x 968 ) / 188760

= 390 / 968

= 390

Step2:

LCM(2, 546) = 546

GCD(2, 546) = ( 2 x 546 ) / 546

= 2 / 546

= 2

Step3:

LCM(2, 947) = 1894

GCD(2, 947) = ( 2 x 947 ) / 1894

= 2 / 947

= 2

So, Greatest Common Divisor of 390, 968, 546, 947 is 1
