Given numbers are 830, 205, 773, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(830, 205) = 34030
GCD(830, 205) = ( 830 x 205 ) / 34030
= 830 / 205
= 830
Step2:
LCM(5, 773) = 3865
GCD(5, 773) = ( 5 x 773 ) / 3865
= 5 / 773
= 5
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 830, 205, 773, 781 is 1
