Given numbers are 298, 615, 609, 858
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(298, 615) = 183270
GCD(298, 615) = ( 298 x 615 ) / 183270
= 298 / 615
= 298
Step2:
LCM(1, 609) = 609
GCD(1, 609) = ( 1 x 609 ) / 609
= 1 / 609
= 1
Step3:
LCM(1, 858) = 858
GCD(1, 858) = ( 1 x 858 ) / 858
= 1 / 858
= 1
So, Greatest Common Divisor of 298, 615, 609, 858 is 1
