Given numbers are 673, 647, 860, 655
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(673, 647) = 435431
GCD(673, 647) = ( 673 x 647 ) / 435431
= 673 / 647
= 673
Step2:
LCM(1, 860) = 860
GCD(1, 860) = ( 1 x 860 ) / 860
= 1 / 860
= 1
Step3:
LCM(1, 655) = 655
GCD(1, 655) = ( 1 x 655 ) / 655
= 1 / 655
= 1
So, Greatest Common Divisor of 673, 647, 860, 655 is 1
