Given numbers are 154, 605, 825, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(154, 605) = 8470
GCD(154, 605) = ( 154 x 605 ) / 8470
= 154 / 605
= 154
Step2:
LCM(11, 825) = 825
GCD(11, 825) = ( 11 x 825 ) / 825
= 11 / 825
= 11
Step3:
LCM(11, 646) = 7106
GCD(11, 646) = ( 11 x 646 ) / 7106
= 11 / 646
= 11
So, Greatest Common Divisor of 154, 605, 825, 646 is 1
