Given numbers are 105, 973, 815, 641
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 973) = 14595
GCD(105, 973) = ( 105 x 973 ) / 14595
= 105 / 973
= 105
Step2:
LCM(7, 815) = 5705
GCD(7, 815) = ( 7 x 815 ) / 5705
= 7 / 815
= 7
Step3:
LCM(1, 641) = 641
GCD(1, 641) = ( 1 x 641 ) / 641
= 1 / 641
= 1
So, Greatest Common Divisor of 105, 973, 815, 641 is 1
