Given numbers are 286, 638, 133, 275
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(286, 638) = 8294
GCD(286, 638) = ( 286 x 638 ) / 8294
= 286 / 638
= 286
Step2:
LCM(22, 133) = 2926
GCD(22, 133) = ( 22 x 133 ) / 2926
= 22 / 133
= 22
Step3:
LCM(1, 275) = 275
GCD(1, 275) = ( 1 x 275 ) / 275
= 1 / 275
= 1
So, Greatest Common Divisor of 286, 638, 133, 275 is 1
