Given numbers are 436, 678, 139, 765

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

Apply this formula for all numbers.

Step1:

LCM(436, 678) = 147804

GCD(436, 678) = ( 436 x 678 ) / 147804

= 436 / 678

= 436

Step2:

LCM(2, 139) = 278

GCD(2, 139) = ( 2 x 139 ) / 278

= 2 / 139

= 2

Step3:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

So, Greatest Common Divisor of 436, 678, 139, 765 is 1
