Given numbers are 617, 286, 815, 790
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(617, 286) = 176462
GCD(617, 286) = ( 617 x 286 ) / 176462
= 617 / 286
= 617
Step2:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
Step3:
LCM(1, 790) = 790
GCD(1, 790) = ( 1 x 790 ) / 790
= 1 / 790
= 1
So, Greatest Common Divisor of 617, 286, 815, 790 is 1
