Given numbers are 211, 655, 947, 831
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(211, 655) = 138205
GCD(211, 655) = ( 211 x 655 ) / 138205
= 211 / 655
= 211
Step2:
LCM(1, 947) = 947
GCD(1, 947) = ( 1 x 947 ) / 947
= 1 / 947
= 1
Step3:
LCM(1, 831) = 831
GCD(1, 831) = ( 1 x 831 ) / 831
= 1 / 831
= 1
So, Greatest Common Divisor of 211, 655, 947, 831 is 1
