Given numbers are 445, 527, 642

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

Apply this formula for all numbers.

Step1:

LCM(445, 527) = 234515

GCD(445, 527) = ( 445 x 527 ) / 234515

= 445 / 527

= 445

Step2:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 445, 527, 642 is 1
