GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(457, 815) = 372455
GCD(457, 815) = ( 457 x 815 ) / 372455
= 457 / 815
= 457
Step2:
LCM(1, 778) = 778
GCD(1, 778) = ( 1 x 778 ) / 778
= 1 / 778
= 1
Step3:
LCM(1, 286) = 286
GCD(1, 286) = ( 1 x 286 ) / 286
= 1 / 286
= 1
So, Greatest Common Divisor of 457, 815, 778, 286 is 1
