Given numbers are 747, 414, 247, 977
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(747, 414) = 34362
GCD(747, 414) = ( 747 x 414 ) / 34362
= 747 / 414
= 747
Step2:
LCM(9, 247) = 2223
GCD(9, 247) = ( 9 x 247 ) / 2223
= 9 / 247
= 9
Step3:
LCM(1, 977) = 977
GCD(1, 977) = ( 1 x 977 ) / 977
= 1 / 977
= 1
So, Greatest Common Divisor of 747, 414, 247, 977 is 1
