Given numbers are 278, 452, 399, 275
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 452) = 62828
GCD(278, 452) = ( 278 x 452 ) / 62828
= 278 / 452
= 278
Step2:
LCM(2, 399) = 798
GCD(2, 399) = ( 2 x 399 ) / 798
= 2 / 399
= 2
Step3:
LCM(1, 275) = 275
GCD(1, 275) = ( 1 x 275 ) / 275
= 1 / 275
= 1
So, Greatest Common Divisor of 278, 452, 399, 275 is 1
