Given numbers are 815, 406, 342, 118
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 406) = 330890
GCD(815, 406) = ( 815 x 406 ) / 330890
= 815 / 406
= 815
Step2:
LCM(1, 342) = 342
GCD(1, 342) = ( 1 x 342 ) / 342
= 1 / 342
= 1
Step3:
LCM(1, 118) = 118
GCD(1, 118) = ( 1 x 118 ) / 118
= 1 / 118
= 1
So, Greatest Common Divisor of 815, 406, 342, 118 is 1
