GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(249, 378) = 31374
GCD(249, 378) = ( 249 x 378 ) / 31374
= 249 / 378
= 249
Step2:
LCM(3, 411) = 411
GCD(3, 411) = ( 3 x 411 ) / 411
= 3 / 411
= 3
Step3:
LCM(3, 807) = 807
GCD(3, 807) = ( 3 x 807 ) / 807
= 3 / 807
= 3
So, Greatest Common Divisor of 249, 378, 411, 807 is 3
