Given numbers are 777, 978, 857, 286

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

Apply this formula for all numbers.

Step1:

LCM(777, 978) = 253302

GCD(777, 978) = ( 777 x 978 ) / 253302

= 777 / 978

= 777

Step2:

LCM(3, 857) = 2571

GCD(3, 857) = ( 3 x 857 ) / 2571

= 3 / 857

= 3

Step3:

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

= 1 / 286

= 1

So, Greatest Common Divisor of 777, 978, 857, 286 is 1
