Given numbers are 785, 128, 644, 332

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

Apply this formula for all numbers.

Step1:

LCM(785, 128) = 100480

GCD(785, 128) = ( 785 x 128 ) / 100480

= 785 / 128

= 785

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 332) = 332

GCD(1, 332) = ( 1 x 332 ) / 332

= 1 / 332

= 1

So, Greatest Common Divisor of 785, 128, 644, 332 is 1
