Given numbers are 775, 265, 575, 643

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

Apply this formula for all numbers.

Step1:

LCM(775, 265) = 41075

GCD(775, 265) = ( 775 x 265 ) / 41075

= 775 / 265

= 775

Step2:

LCM(5, 575) = 575

GCD(5, 575) = ( 5 x 575 ) / 575

= 5 / 575

= 5

Step3:

LCM(5, 643) = 3215

GCD(5, 643) = ( 5 x 643 ) / 3215

= 5 / 643

= 5

So, Greatest Common Divisor of 775, 265, 575, 643 is 1
