Given numbers are 105, 785, 643, 974
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 785) = 16485
GCD(105, 785) = ( 105 x 785 ) / 16485
= 105 / 785
= 105
Step2:
LCM(5, 643) = 3215
GCD(5, 643) = ( 5 x 643 ) / 3215
= 5 / 643
= 5
Step3:
LCM(1, 974) = 974
GCD(1, 974) = ( 1 x 974 ) / 974
= 1 / 974
= 1
So, Greatest Common Divisor of 105, 785, 643, 974 is 1
