Given numbers are 947, 109, 78, 992

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

Apply this formula for all numbers.

Step1:

LCM(947, 109) = 103223

GCD(947, 109) = ( 947 x 109 ) / 103223

= 947 / 109

= 947

Step2:

LCM(1, 78) = 78

GCD(1, 78) = ( 1 x 78 ) / 78

= 1 / 78

= 1

Step3:

LCM(1, 992) = 992

GCD(1, 992) = ( 1 x 992 ) / 992

= 1 / 992

= 1

So, Greatest Common Divisor of 947, 109, 78, 992 is 1
