Given numbers are 644, 911, 711, 435

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

Apply this formula for all numbers.

Step1:

LCM(644, 911) = 586684

GCD(644, 911) = ( 644 x 911 ) / 586684

= 644 / 911

= 644

Step2:

LCM(1, 711) = 711

GCD(1, 711) = ( 1 x 711 ) / 711

= 1 / 711

= 1

Step3:

LCM(1, 435) = 435

GCD(1, 435) = ( 1 x 435 ) / 435

= 1 / 435

= 1

So, Greatest Common Divisor of 644, 911, 711, 435 is 1
