Given numbers are 297, 861, 615, 100
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(297, 861) = 85239
GCD(297, 861) = ( 297 x 861 ) / 85239
= 297 / 861
= 297
Step2:
LCM(3, 615) = 615
GCD(3, 615) = ( 3 x 615 ) / 615
= 3 / 615
= 3
Step3:
LCM(3, 100) = 300
GCD(3, 100) = ( 3 x 100 ) / 300
= 3 / 100
= 3
So, Greatest Common Divisor of 297, 861, 615, 100 is 1
