Given numbers are 394, 478, 780, 725
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(394, 478) = 94166
GCD(394, 478) = ( 394 x 478 ) / 94166
= 394 / 478
= 394
Step2:
LCM(2, 780) = 780
GCD(2, 780) = ( 2 x 780 ) / 780
= 2 / 780
= 2
Step3:
LCM(2, 725) = 1450
GCD(2, 725) = ( 2 x 725 ) / 1450
= 2 / 725
= 2
So, Greatest Common Divisor of 394, 478, 780, 725 is 1
