GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(747, 889) = 664083
GCD(747, 889) = ( 747 x 889 ) / 664083
= 747 / 889
= 747
Step2:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
Step3:
LCM(1, 786) = 786
GCD(1, 786) = ( 1 x 786 ) / 786
= 1 / 786
= 1
So, Greatest Common Divisor of 747, 889, 257, 786 is 1
