Given numbers are 410, 778, 978, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(410, 778) = 159490
GCD(410, 778) = ( 410 x 778 ) / 159490
= 410 / 778
= 410
Step2:
LCM(2, 978) = 978
GCD(2, 978) = ( 2 x 978 ) / 978
= 2 / 978
= 2
Step3:
LCM(2, 689) = 1378
GCD(2, 689) = ( 2 x 689 ) / 1378
= 2 / 689
= 2
So, Greatest Common Divisor of 410, 778, 978, 689 is 1
