Given numbers are 130, 780, 378, 843
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(130, 780) = 780
GCD(130, 780) = ( 130 x 780 ) / 780
= 130 / 780
= 130
Step2:
LCM(130, 378) = 24570
GCD(130, 378) = ( 130 x 378 ) / 24570
= 130 / 378
= 130
Step3:
LCM(2, 843) = 1686
GCD(2, 843) = ( 2 x 843 ) / 1686
= 2 / 843
= 2
So, Greatest Common Divisor of 130, 780, 378, 843 is 1
