Given numbers are 425, 901, 897, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(425, 901) = 22525
GCD(425, 901) = ( 425 x 901 ) / 22525
= 425 / 901
= 425
Step2:
LCM(17, 897) = 15249
GCD(17, 897) = ( 17 x 897 ) / 15249
= 17 / 897
= 17
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 425, 901, 897, 420 is 1
