Given numbers are 820, 975, 838

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(820, 975) = 159900

GCD(820, 975) = ( 820 x 975 ) / 159900

= 820 / 975

= 820

Step2:

LCM(5, 838) = 4190

GCD(5, 838) = ( 5 x 838 ) / 4190

= 5 / 838

= 5

So, Greatest Common Divisor of 820, 975, 838 is 1
