GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 586) = 116614
GCD(398, 586) = ( 398 x 586 ) / 116614
= 398 / 586
= 398
Step2:
LCM(2, 489) = 978
GCD(2, 489) = ( 2 x 489 ) / 978
= 2 / 489
= 2
Step3:
LCM(1, 125) = 125
GCD(1, 125) = ( 1 x 125 ) / 125
= 1 / 125
= 1
So, Greatest Common Divisor of 398, 586, 489, 125 is 1
