Given numbers are 450, 280, 475, 978
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(450, 280) = 12600
GCD(450, 280) = ( 450 x 280 ) / 12600
= 450 / 280
= 450
Step2:
LCM(10, 475) = 950
GCD(10, 475) = ( 10 x 475 ) / 950
= 10 / 475
= 10
Step3:
LCM(5, 978) = 4890
GCD(5, 978) = ( 5 x 978 ) / 4890
= 5 / 978
= 5
So, Greatest Common Divisor of 450, 280, 475, 978 is 1
