Given numbers are 844, 408, 480, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(844, 408) = 86088
GCD(844, 408) = ( 844 x 408 ) / 86088
= 844 / 408
= 844
Step2:
LCM(4, 480) = 480
GCD(4, 480) = ( 4 x 480 ) / 480
= 4 / 480
= 4
Step3:
LCM(4, 643) = 2572
GCD(4, 643) = ( 4 x 643 ) / 2572
= 4 / 643
= 4
So, Greatest Common Divisor of 844, 408, 480, 643 is 1
