Given numbers are 130, 308, 819, 784
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(130, 308) = 20020
GCD(130, 308) = ( 130 x 308 ) / 20020
= 130 / 308
= 130
Step2:
LCM(2, 819) = 1638
GCD(2, 819) = ( 2 x 819 ) / 1638
= 2 / 819
= 2
Step3:
LCM(1, 784) = 784
GCD(1, 784) = ( 1 x 784 ) / 784
= 1 / 784
= 1
So, Greatest Common Divisor of 130, 308, 819, 784 is 1
