Given numbers are 645, 723, 356, 783

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

Apply this formula for all numbers.

Step1:

LCM(645, 723) = 155445

GCD(645, 723) = ( 645 x 723 ) / 155445

= 645 / 723

= 645

Step2:

LCM(3, 356) = 1068

GCD(3, 356) = ( 3 x 356 ) / 1068

= 3 / 356

= 3

Step3:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

So, Greatest Common Divisor of 645, 723, 356, 783 is 1
