Given numbers are 115, 790, 151, 665
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(115, 790) = 18170
GCD(115, 790) = ( 115 x 790 ) / 18170
= 115 / 790
= 115
Step2:
LCM(5, 151) = 755
GCD(5, 151) = ( 5 x 151 ) / 755
= 5 / 151
= 5
Step3:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
So, Greatest Common Divisor of 115, 790, 151, 665 is 1
