GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(777, 981) = 254079
GCD(777, 981) = ( 777 x 981 ) / 254079
= 777 / 981
= 777
Step2:
LCM(3, 856) = 2568
GCD(3, 856) = ( 3 x 856 ) / 2568
= 3 / 856
= 3
Step3:
LCM(1, 356) = 356
GCD(1, 356) = ( 1 x 356 ) / 356
= 1 / 356
= 1
So, Greatest Common Divisor of 777, 981, 856, 356 is 1
