GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 372) = 39804
GCD(428, 372) = ( 428 x 372 ) / 39804
= 428 / 372
= 428
Step2:
LCM(4, 908) = 908
GCD(4, 908) = ( 4 x 908 ) / 908
= 4 / 908
= 4
Step3:
LCM(4, 731) = 2924
GCD(4, 731) = ( 4 x 731 ) / 2924
= 4 / 731
= 4
So, Greatest Common Divisor of 428, 372, 908, 731 is 1
