Given numbers are 644, 220, 452, 500
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 220) = 35420
GCD(644, 220) = ( 644 x 220 ) / 35420
= 644 / 220
= 644
Step2:
LCM(4, 452) = 452
GCD(4, 452) = ( 4 x 452 ) / 452
= 4 / 452
= 4
Step3:
LCM(4, 500) = 500
GCD(4, 500) = ( 4 x 500 ) / 500
= 4 / 500
= 4
So, Greatest Common Divisor of 644, 220, 452, 500 is 4
