GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(294, 728) = 15288
GCD(294, 728) = ( 294 x 728 ) / 15288
= 294 / 728
= 294
Step2:
LCM(14, 391) = 5474
GCD(14, 391) = ( 14 x 391 ) / 5474
= 14 / 391
= 14
Step3:
LCM(1, 378) = 378
GCD(1, 378) = ( 1 x 378 ) / 378
= 1 / 378
= 1
So, Greatest Common Divisor of 294, 728, 391, 378 is 1
