Given numbers are 643, 408, 786, 701

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

Apply this formula for all numbers.

Step1:

LCM(643, 408) = 262344

GCD(643, 408) = ( 643 x 408 ) / 262344

= 643 / 408

= 643

Step2:

LCM(1, 786) = 786

GCD(1, 786) = ( 1 x 786 ) / 786

= 1 / 786

= 1

Step3:

LCM(1, 701) = 701

GCD(1, 701) = ( 1 x 701 ) / 701

= 1 / 701

= 1

So, Greatest Common Divisor of 643, 408, 786, 701 is 1
