Given numbers are 978, 658, 218, 301
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 658) = 321762
GCD(978, 658) = ( 978 x 658 ) / 321762
= 978 / 658
= 978
Step2:
LCM(2, 218) = 218
GCD(2, 218) = ( 2 x 218 ) / 218
= 2 / 218
= 2
Step3:
LCM(2, 301) = 602
GCD(2, 301) = ( 2 x 301 ) / 602
= 2 / 301
= 2
So, Greatest Common Divisor of 978, 658, 218, 301 is 1
