Given numbers are 280, 108, 272, 393
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 108) = 7560
GCD(280, 108) = ( 280 x 108 ) / 7560
= 280 / 108
= 280
Step2:
LCM(4, 272) = 272
GCD(4, 272) = ( 4 x 272 ) / 272
= 4 / 272
= 4
Step3:
LCM(4, 393) = 1572
GCD(4, 393) = ( 4 x 393 ) / 1572
= 4 / 393
= 4
So, Greatest Common Divisor of 280, 108, 272, 393 is 1
