HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 808, 653 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 808, 653 is 1 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 808, 653 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 808, 653 is 1.
HCF(808, 653) = 1
HCF of 808, 653 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 808, 653 is 1.
Highest Common Factor of 808,653 is 1
Step 1: Since 808 > 653, we apply the division lemma to 808 and 653, to get
808 = 653 x 1 + 155
Step 2: Since the reminder 653 ≠ 0, we apply division lemma to 155 and 653, to get
653 = 155 x 4 + 33
Step 3: We consider the new divisor 155 and the new remainder 33, and apply the division lemma to get
155 = 33 x 4 + 23
We consider the new divisor 33 and the new remainder 23,and apply the division lemma to get
33 = 23 x 1 + 10
We consider the new divisor 23 and the new remainder 10,and apply the division lemma to get
23 = 10 x 2 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 808 and 653 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(23,10) = HCF(33,23) = HCF(155,33) = HCF(653,155) = HCF(808,653) .
