Given numbers are 470, 875, 215, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(470, 875) = 82250
GCD(470, 875) = ( 470 x 875 ) / 82250
= 470 / 875
= 470
Step2:
LCM(5, 215) = 215
GCD(5, 215) = ( 5 x 215 ) / 215
= 5 / 215
= 5
Step3:
LCM(5, 644) = 3220
GCD(5, 644) = ( 5 x 644 ) / 3220
= 5 / 644
= 5
So, Greatest Common Divisor of 470, 875, 215, 644 is 1
