Given numbers are 640, 910, 872, 672
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 910) = 58240
GCD(640, 910) = ( 640 x 910 ) / 58240
= 640 / 910
= 640
Step2:
LCM(10, 872) = 4360
GCD(10, 872) = ( 10 x 872 ) / 4360
= 10 / 872
= 10
Step3:
LCM(2, 672) = 672
GCD(2, 672) = ( 2 x 672 ) / 672
= 2 / 672
= 2
So, Greatest Common Divisor of 640, 910, 872, 672 is 2
