Given numbers are 130, 780, 613, 867
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, 613) = 79690
GCD(130, 613) = ( 130 x 613 ) / 79690
= 130 / 613
= 130
Step3:
LCM(1, 867) = 867
GCD(1, 867) = ( 1 x 867 ) / 867
= 1 / 867
= 1
So, Greatest Common Divisor of 130, 780, 613, 867 is 1
