Given numbers are 958, 780, 306, 805
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(958, 780) = 373620
GCD(958, 780) = ( 958 x 780 ) / 373620
= 958 / 780
= 958
Step2:
LCM(2, 306) = 306
GCD(2, 306) = ( 2 x 306 ) / 306
= 2 / 306
= 2
Step3:
LCM(2, 805) = 1610
GCD(2, 805) = ( 2 x 805 ) / 1610
= 2 / 805
= 2
So, Greatest Common Divisor of 958, 780, 306, 805 is 1
