Given numbers are 115, 190, 307, 857
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(115, 190) = 4370
GCD(115, 190) = ( 115 x 190 ) / 4370
= 115 / 190
= 115
Step2:
LCM(5, 307) = 1535
GCD(5, 307) = ( 5 x 307 ) / 1535
= 5 / 307
= 5
Step3:
LCM(1, 857) = 857
GCD(1, 857) = ( 1 x 857 ) / 857
= 1 / 857
= 1
So, Greatest Common Divisor of 115, 190, 307, 857 is 1
