HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 490, 816, 664 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 490, 816, 664 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 490, 816, 664 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 490, 816, 664 is 2.
HCF(490, 816, 664) = 2
HCF of 490, 816, 664 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 490, 816, 664 is 2.
Highest Common Factor of 490,816,664 is 2
Step 1: Since 816 > 490, we apply the division lemma to 816 and 490, to get
816 = 490 x 1 + 326
Step 2: Since the reminder 490 ≠ 0, we apply division lemma to 326 and 490, to get
490 = 326 x 1 + 164
Step 3: We consider the new divisor 326 and the new remainder 164, and apply the division lemma to get
326 = 164 x 1 + 162
We consider the new divisor 164 and the new remainder 162,and apply the division lemma to get
164 = 162 x 1 + 2
We consider the new divisor 162 and the new remainder 2,and apply the division lemma to get
162 = 2 x 81 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 490 and 816 is 2
Notice that 2 = HCF(162,2) = HCF(164,162) = HCF(326,164) = HCF(490,326) = HCF(816,490) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 664 > 2, we apply the division lemma to 664 and 2, to get
664 = 2 x 332 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 664 is 2
Notice that 2 = HCF(664,2) .
