Given numbers are 249, 390, 667, 855
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(249, 390) = 32370
GCD(249, 390) = ( 249 x 390 ) / 32370
= 249 / 390
= 249
Step2:
LCM(3, 667) = 2001
GCD(3, 667) = ( 3 x 667 ) / 2001
= 3 / 667
= 3
Step3:
LCM(1, 855) = 855
GCD(1, 855) = ( 1 x 855 ) / 855
= 1 / 855
= 1
So, Greatest Common Divisor of 249, 390, 667, 855 is 1
