HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 666, 688, 816, 826 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 666, 688, 816, 826 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 666, 688, 816, 826 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 666, 688, 816, 826 is 2.
HCF(666, 688, 816, 826) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 666, 688, 816, 826 is 2.
Step 1: Since 688 > 666, we apply the division lemma to 688 and 666, to get
688 = 666 x 1 + 22
Step 2: Since the reminder 666 ≠ 0, we apply division lemma to 22 and 666, to get
666 = 22 x 30 + 6
Step 3: We consider the new divisor 22 and the new remainder 6, and apply the division lemma to get
22 = 6 x 3 + 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 666 and 688 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(22,6) = HCF(666,22) = HCF(688,666) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 816 > 2, we apply the division lemma to 816 and 2, to get
816 = 2 x 408 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 816 is 2
Notice that 2 = HCF(816,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 826 > 2, we apply the division lemma to 826 and 2, to get
826 = 2 x 413 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 826 is 2
Notice that 2 = HCF(826,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
