Given numbers are 543, 204, 259, 640
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(543, 204) = 36924
GCD(543, 204) = ( 543 x 204 ) / 36924
= 543 / 204
= 543
Step2:
LCM(3, 259) = 777
GCD(3, 259) = ( 3 x 259 ) / 777
= 3 / 259
= 3
Step3:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
So, Greatest Common Divisor of 543, 204, 259, 640 is 1
