Given numbers are 830, 875, 838, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(830, 875) = 145250
GCD(830, 875) = ( 830 x 875 ) / 145250
= 830 / 875
= 830
Step2:
LCM(5, 838) = 4190
GCD(5, 838) = ( 5 x 838 ) / 4190
= 5 / 838
= 5
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 830, 875, 838, 638 is 1
