Given numbers are 644, 312, 352, 787

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

Apply this formula for all numbers.

Step1:

LCM(644, 312) = 50232

GCD(644, 312) = ( 644 x 312 ) / 50232

= 644 / 312

= 644

Step2:

LCM(4, 352) = 352

GCD(4, 352) = ( 4 x 352 ) / 352

= 4 / 352

= 4

Step3:

LCM(4, 787) = 3148

GCD(4, 787) = ( 4 x 787 ) / 3148

= 4 / 787

= 4

So, Greatest Common Divisor of 644, 312, 352, 787 is 1
