Given numbers are 147, 786, 649, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(147, 786) = 38514
GCD(147, 786) = ( 147 x 786 ) / 38514
= 147 / 786
= 147
Step2:
LCM(3, 649) = 1947
GCD(3, 649) = ( 3 x 649 ) / 1947
= 3 / 649
= 3
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 147, 786, 649, 257 is 1
