Given numbers are 862, 945, 615, 312
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(862, 945) = 814590
GCD(862, 945) = ( 862 x 945 ) / 814590
= 862 / 945
= 862
Step2:
LCM(1, 615) = 615
GCD(1, 615) = ( 1 x 615 ) / 615
= 1 / 615
= 1
Step3:
LCM(1, 312) = 312
GCD(1, 312) = ( 1 x 312 ) / 312
= 1 / 312
= 1
So, Greatest Common Divisor of 862, 945, 615, 312 is 1
