Given numbers are 785, 890, 644, 767

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

Apply this formula for all numbers.

Step1:

LCM(785, 890) = 139730

GCD(785, 890) = ( 785 x 890 ) / 139730

= 785 / 890

= 785

Step2:

LCM(5, 644) = 3220

GCD(5, 644) = ( 5 x 644 ) / 3220

= 5 / 644

= 5

Step3:

LCM(1, 767) = 767

GCD(1, 767) = ( 1 x 767 ) / 767

= 1 / 767

= 1

So, Greatest Common Divisor of 785, 890, 644, 767 is 1
