GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(249, 783) = 64989
GCD(249, 783) = ( 249 x 783 ) / 64989
= 249 / 783
= 249
Step2:
LCM(3, 447) = 447
GCD(3, 447) = ( 3 x 447 ) / 447
= 3 / 447
= 3
Step3:
LCM(3, 127) = 381
GCD(3, 127) = ( 3 x 127 ) / 381
= 3 / 127
= 3
So, Greatest Common Divisor of 249, 783, 447, 127 is 1
