GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(297, 771) = 76329
GCD(297, 771) = ( 297 x 771 ) / 76329
= 297 / 771
= 297
Step2:
LCM(3, 991) = 2973
GCD(3, 991) = ( 3 x 991 ) / 2973
= 3 / 991
= 3
Step3:
LCM(1, 216) = 216
GCD(1, 216) = ( 1 x 216 ) / 216
= 1 / 216
= 1
So, Greatest Common Divisor of 297, 771, 991, 216 is 1
