Given numbers are 978, 794, 425, 218
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 794) = 388266
GCD(978, 794) = ( 978 x 794 ) / 388266
= 978 / 794
= 978
Step2:
LCM(2, 425) = 850
GCD(2, 425) = ( 2 x 425 ) / 850
= 2 / 425
= 2
Step3:
LCM(1, 218) = 218
GCD(1, 218) = ( 1 x 218 ) / 218
= 1 / 218
= 1
So, Greatest Common Divisor of 978, 794, 425, 218 is 1
