Given numbers are 640, 307, 205, 227
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 307) = 196480
GCD(640, 307) = ( 640 x 307 ) / 196480
= 640 / 307
= 640
Step2:
LCM(1, 205) = 205
GCD(1, 205) = ( 1 x 205 ) / 205
= 1 / 205
= 1
Step3:
LCM(1, 227) = 227
GCD(1, 227) = ( 1 x 227 ) / 227
= 1 / 227
= 1
So, Greatest Common Divisor of 640, 307, 205, 227 is 1
