Given numbers are 643, 555, 782, 777

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

Apply this formula for all numbers.

Step1:

LCM(643, 555) = 356865

GCD(643, 555) = ( 643 x 555 ) / 356865

= 643 / 555

= 643

Step2:

LCM(1, 782) = 782

GCD(1, 782) = ( 1 x 782 ) / 782

= 1 / 782

= 1

Step3:

LCM(1, 777) = 777

GCD(1, 777) = ( 1 x 777 ) / 777

= 1 / 777

= 1

So, Greatest Common Divisor of 643, 555, 782, 777 is 1
