Given numbers are 978, 513, 498, 220
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 513) = 167238
GCD(978, 513) = ( 978 x 513 ) / 167238
= 978 / 513
= 978
Step2:
LCM(3, 498) = 498
GCD(3, 498) = ( 3 x 498 ) / 498
= 3 / 498
= 3
Step3:
LCM(3, 220) = 660
GCD(3, 220) = ( 3 x 220 ) / 660
= 3 / 220
= 3
So, Greatest Common Divisor of 978, 513, 498, 220 is 1
