Given numbers are 249, 159, 142, 280
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(249, 159) = 13197
GCD(249, 159) = ( 249 x 159 ) / 13197
= 249 / 159
= 249
Step2:
LCM(3, 142) = 426
GCD(3, 142) = ( 3 x 142 ) / 426
= 3 / 142
= 3
Step3:
LCM(1, 280) = 280
GCD(1, 280) = ( 1 x 280 ) / 280
= 1 / 280
= 1
So, Greatest Common Divisor of 249, 159, 142, 280 is 1
