Given numbers are 640, 223, 879, 230
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 223) = 142720
GCD(640, 223) = ( 640 x 223 ) / 142720
= 640 / 223
= 640
Step2:
LCM(1, 879) = 879
GCD(1, 879) = ( 1 x 879 ) / 879
= 1 / 879
= 1
Step3:
LCM(1, 230) = 230
GCD(1, 230) = ( 1 x 230 ) / 230
= 1 / 230
= 1
So, Greatest Common Divisor of 640, 223, 879, 230 is 1
