Given numbers are 978, 815, 474, 856
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 815) = 4890
GCD(978, 815) = ( 978 x 815 ) / 4890
= 978 / 815
= 978
Step2:
LCM(163, 474) = 77262
GCD(163, 474) = ( 163 x 474 ) / 77262
= 163 / 474
= 163
Step3:
LCM(1, 856) = 856
GCD(1, 856) = ( 1 x 856 ) / 856
= 1 / 856
= 1
So, Greatest Common Divisor of 978, 815, 474, 856 is 1
