Given numbers are 402, 826, 980, 515
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(402, 826) = 166026
GCD(402, 826) = ( 402 x 826 ) / 166026
= 402 / 826
= 402
Step2:
LCM(2, 980) = 980
GCD(2, 980) = ( 2 x 980 ) / 980
= 2 / 980
= 2
Step3:
LCM(2, 515) = 1030
GCD(2, 515) = ( 2 x 515 ) / 1030
= 2 / 515
= 2
So, Greatest Common Divisor of 402, 826, 980, 515 is 1
