Given numbers are 198, 620, 905, 830
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(198, 620) = 61380
GCD(198, 620) = ( 198 x 620 ) / 61380
= 198 / 620
= 198
Step2:
LCM(2, 905) = 1810
GCD(2, 905) = ( 2 x 905 ) / 1810
= 2 / 905
= 2
Step3:
LCM(1, 830) = 830
GCD(1, 830) = ( 1 x 830 ) / 830
= 1 / 830
= 1
So, Greatest Common Divisor of 198, 620, 905, 830 is 1
