HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 450, 477 i.e. 9 the largest integer that leaves a remainder zero for all numbers.
HCF of 450, 477 is 9 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 450, 477 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 450, 477 is 9.
HCF(450, 477) = 9
HCF of 450, 477 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 450, 477 is 9.
Highest Common Factor of 450,477 is 9
Step 1: Since 477 > 450, we apply the division lemma to 477 and 450, to get
477 = 450 x 1 + 27
Step 2: Since the reminder 450 ≠ 0, we apply division lemma to 27 and 450, to get
450 = 27 x 16 + 18
Step 3: We consider the new divisor 27 and the new remainder 18, and apply the division lemma to get
27 = 18 x 1 + 9
We consider the new divisor 18 and the new remainder 9, and apply the division lemma to get
18 = 9 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 450 and 477 is 9
Notice that 9 = HCF(18,9) = HCF(27,18) = HCF(450,27) = HCF(477,450) .
