Given numbers are 777, 261, 530, 947
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(777, 261) = 67599
GCD(777, 261) = ( 777 x 261 ) / 67599
= 777 / 261
= 777
Step2:
LCM(3, 530) = 1590
GCD(3, 530) = ( 3 x 530 ) / 1590
= 3 / 530
= 3
Step3:
LCM(1, 947) = 947
GCD(1, 947) = ( 1 x 947 ) / 947
= 1 / 947
= 1
So, Greatest Common Divisor of 777, 261, 530, 947 is 1
