Given numbers are 644, 745, 687, 873
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 745) = 479780
GCD(644, 745) = ( 644 x 745 ) / 479780
= 644 / 745
= 644
Step2:
LCM(1, 687) = 687
GCD(1, 687) = ( 1 x 687 ) / 687
= 1 / 687
= 1
Step3:
LCM(1, 873) = 873
GCD(1, 873) = ( 1 x 873 ) / 873
= 1 / 873
= 1
So, Greatest Common Divisor of 644, 745, 687, 873 is 1
