HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 456, 478 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 456, 478 is 2 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 456, 478 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 456, 478 is 2.
HCF(456, 478) = 2
HCF of 456, 478 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 456, 478 is 2.
Highest Common Factor of 456,478 is 2
Step 1: Since 478 > 456, we apply the division lemma to 478 and 456, to get
478 = 456 x 1 + 22
Step 2: Since the reminder 456 ≠ 0, we apply division lemma to 22 and 456, to get
456 = 22 x 20 + 16
Step 3: We consider the new divisor 22 and the new remainder 16, and apply the division lemma to get
22 = 16 x 1 + 6
We consider the new divisor 16 and the new remainder 6,and apply the division lemma to get
16 = 6 x 2 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 456 and 478 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(22,16) = HCF(456,22) = HCF(478,456) .
