HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 782, 464 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 782, 464 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 782, 464 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 782, 464 is 2.
HCF(782, 464) = 2
HCF of 782, 464 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 782, 464 is 2.
Highest Common Factor of 782,464 is 2
Step 1: Since 782 > 464, we apply the division lemma to 782 and 464, to get
782 = 464 x 1 + 318
Step 2: Since the reminder 464 ≠ 0, we apply division lemma to 318 and 464, to get
464 = 318 x 1 + 146
Step 3: We consider the new divisor 318 and the new remainder 146, and apply the division lemma to get
318 = 146 x 2 + 26
We consider the new divisor 146 and the new remainder 26,and apply the division lemma to get
146 = 26 x 5 + 16
We consider the new divisor 26 and the new remainder 16,and apply the division lemma to get
26 = 16 x 1 + 10
We consider the new divisor 16 and the new remainder 10,and apply the division lemma to get
16 = 10 x 1 + 6
We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get
10 = 6 x 1 + 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 782 and 464 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(16,10) = HCF(26,16) = HCF(146,26) = HCF(318,146) = HCF(464,318) = HCF(782,464) .
