Given numbers are 640, 250, 823, 847
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 250) = 16000
GCD(640, 250) = ( 640 x 250 ) / 16000
= 640 / 250
= 640
Step2:
LCM(10, 823) = 8230
GCD(10, 823) = ( 10 x 823 ) / 8230
= 10 / 823
= 10
Step3:
LCM(1, 847) = 847
GCD(1, 847) = ( 1 x 847 ) / 847
= 1 / 847
= 1
So, Greatest Common Divisor of 640, 250, 823, 847 is 1
