Given numbers are 195, 640, 447, 725
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(195, 640) = 24960
GCD(195, 640) = ( 195 x 640 ) / 24960
= 195 / 640
= 195
Step2:
LCM(5, 447) = 2235
GCD(5, 447) = ( 5 x 447 ) / 2235
= 5 / 447
= 5
Step3:
LCM(1, 725) = 725
GCD(1, 725) = ( 1 x 725 ) / 725
= 1 / 725
= 1
So, Greatest Common Divisor of 195, 640, 447, 725 is 1
