Given numbers are 249, 615, 102, 431
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(249, 615) = 51045
GCD(249, 615) = ( 249 x 615 ) / 51045
= 249 / 615
= 249
Step2:
LCM(3, 102) = 102
GCD(3, 102) = ( 3 x 102 ) / 102
= 3 / 102
= 3
Step3:
LCM(3, 431) = 1293
GCD(3, 431) = ( 3 x 431 ) / 1293
= 3 / 431
= 3
So, Greatest Common Divisor of 249, 615, 102, 431 is 1
