Given numbers are 126, 872, 780, 515
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(126, 872) = 54936
GCD(126, 872) = ( 126 x 872 ) / 54936
= 126 / 872
= 126
Step2:
LCM(2, 780) = 780
GCD(2, 780) = ( 2 x 780 ) / 780
= 2 / 780
= 2
Step3:
LCM(2, 515) = 1030
GCD(2, 515) = ( 2 x 515 ) / 1030
= 2 / 515
= 2
So, Greatest Common Divisor of 126, 872, 780, 515 is 1
