GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(844, 164) = 34604
GCD(844, 164) = ( 844 x 164 ) / 34604
= 844 / 164
= 844
Step2:
LCM(4, 945) = 3780
GCD(4, 945) = ( 4 x 945 ) / 3780
= 4 / 945
= 4
Step3:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
So, Greatest Common Divisor of 844, 164, 945, 978 is 1
