Given numbers are 105, 962, 643, 669
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 962) = 101010
GCD(105, 962) = ( 105 x 962 ) / 101010
= 105 / 962
= 105
Step2:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
Step3:
LCM(1, 669) = 669
GCD(1, 669) = ( 1 x 669 ) / 669
= 1 / 669
= 1
So, Greatest Common Divisor of 105, 962, 643, 669 is 1
