GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 342) = 47538
GCD(278, 342) = ( 278 x 342 ) / 47538
= 278 / 342
= 278
Step2:
LCM(2, 484) = 484
GCD(2, 484) = ( 2 x 484 ) / 484
= 2 / 484
= 2
Step3:
LCM(2, 175) = 350
GCD(2, 175) = ( 2 x 175 ) / 350
= 2 / 175
= 2
So, Greatest Common Divisor of 278, 342, 484, 175 is 1
