Given numbers are 747, 923, 920, 830

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

Apply this formula for all numbers.

Step1:

LCM(747, 923) = 689481

GCD(747, 923) = ( 747 x 923 ) / 689481

= 747 / 923

= 747

Step2:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

Step3:

LCM(1, 830) = 830

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

= 1 / 830

= 1

So, Greatest Common Divisor of 747, 923, 920, 830 is 1
