GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(858, 309) = 88374
GCD(858, 309) = ( 858 x 309 ) / 88374
= 858 / 309
= 858
Step2:
LCM(3, 205) = 615
GCD(3, 205) = ( 3 x 205 ) / 615
= 3 / 205
= 3
Step3:
LCM(1, 768) = 768
GCD(1, 768) = ( 1 x 768 ) / 768
= 1 / 768
= 1
So, Greatest Common Divisor of 858, 309, 205, 768 is 1
