Given numbers are 620, 112, 398, 835
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 112) = 17360
GCD(620, 112) = ( 620 x 112 ) / 17360
= 620 / 112
= 620
Step2:
LCM(4, 398) = 796
GCD(4, 398) = ( 4 x 398 ) / 796
= 4 / 398
= 4
Step3:
LCM(2, 835) = 1670
GCD(2, 835) = ( 2 x 835 ) / 1670
= 2 / 835
= 2
So, Greatest Common Divisor of 620, 112, 398, 835 is 1
