Given numbers are 220, 325, 662, 978
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(220, 325) = 14300
GCD(220, 325) = ( 220 x 325 ) / 14300
= 220 / 325
= 220
Step2:
LCM(5, 662) = 3310
GCD(5, 662) = ( 5 x 662 ) / 3310
= 5 / 662
= 5
Step3:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
So, Greatest Common Divisor of 220, 325, 662, 978 is 1
