Given numbers are 407, 418, 248, 142
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(407, 418) = 15466
GCD(407, 418) = ( 407 x 418 ) / 15466
= 407 / 418
= 407
Step2:
LCM(11, 248) = 2728
GCD(11, 248) = ( 11 x 248 ) / 2728
= 11 / 248
= 11
Step3:
LCM(1, 142) = 142
GCD(1, 142) = ( 1 x 142 ) / 142
= 1 / 142
= 1
So, Greatest Common Divisor of 407, 418, 248, 142 is 1
