Given numbers are 442, 325, 765, 771

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

Apply this formula for all numbers.

Step1:

LCM(442, 325) = 11050

GCD(442, 325) = ( 442 x 325 ) / 11050

= 442 / 325

= 442

Step2:

LCM(13, 765) = 9945

GCD(13, 765) = ( 13 x 765 ) / 9945

= 13 / 765

= 13

Step3:

LCM(1, 771) = 771

GCD(1, 771) = ( 1 x 771 ) / 771

= 1 / 771

= 1

So, Greatest Common Divisor of 442, 325, 765, 771 is 1
