Given numbers are 394, 715, 420, 496
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(394, 715) = 281710
GCD(394, 715) = ( 394 x 715 ) / 281710
= 394 / 715
= 394
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
Step3:
LCM(1, 496) = 496
GCD(1, 496) = ( 1 x 496 ) / 496
= 1 / 496
= 1
So, Greatest Common Divisor of 394, 715, 420, 496 is 1
