Given numbers are 643, 564, 922, 361

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

Apply this formula for all numbers.

Step1:

LCM(643, 564) = 362652

GCD(643, 564) = ( 643 x 564 ) / 362652

= 643 / 564

= 643

Step2:

LCM(1, 922) = 922

GCD(1, 922) = ( 1 x 922 ) / 922

= 1 / 922

= 1

Step3:

LCM(1, 361) = 361

GCD(1, 361) = ( 1 x 361 ) / 361

= 1 / 361

= 1

So, Greatest Common Divisor of 643, 564, 922, 361 is 1
