Given numbers are 670, 643, 853, 955
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(670, 643) = 430810
GCD(670, 643) = ( 670 x 643 ) / 430810
= 670 / 643
= 670
Step2:
LCM(1, 853) = 853
GCD(1, 853) = ( 1 x 853 ) / 853
= 1 / 853
= 1
Step3:
LCM(1, 955) = 955
GCD(1, 955) = ( 1 x 955 ) / 955
= 1 / 955
= 1
So, Greatest Common Divisor of 670, 643, 853, 955 is 1
