Given numbers are 891, 747, 38, 830

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

Apply this formula for all numbers.

Step1:

LCM(891, 747) = 73953

GCD(891, 747) = ( 891 x 747 ) / 73953

= 891 / 747

= 891

Step2:

LCM(9, 38) = 342

GCD(9, 38) = ( 9 x 38 ) / 342

= 9 / 38

= 9

Step3:

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

= 1 / 830

= 1

So, Greatest Common Divisor of 891, 747, 38, 830 is 1
