Given numbers are 687, 382, 857, 115
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 382) = 262434
GCD(687, 382) = ( 687 x 382 ) / 262434
= 687 / 382
= 687
Step2:
LCM(1, 857) = 857
GCD(1, 857) = ( 1 x 857 ) / 857
= 1 / 857
= 1
Step3:
LCM(1, 115) = 115
GCD(1, 115) = ( 1 x 115 ) / 115
= 1 / 115
= 1
So, Greatest Common Divisor of 687, 382, 857, 115 is 1
