HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 653, 406, 916 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 653, 406, 916 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 653, 406, 916 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 653, 406, 916 is 1.
HCF(653, 406, 916) = 1
HCF of 653, 406, 916 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 653, 406, 916 is 1.
Highest Common Factor of 653,406,916 is 1
Step 1: Since 653 > 406, we apply the division lemma to 653 and 406, to get
653 = 406 x 1 + 247
Step 2: Since the reminder 406 ≠ 0, we apply division lemma to 247 and 406, to get
406 = 247 x 1 + 159
Step 3: We consider the new divisor 247 and the new remainder 159, and apply the division lemma to get
247 = 159 x 1 + 88
We consider the new divisor 159 and the new remainder 88,and apply the division lemma to get
159 = 88 x 1 + 71
We consider the new divisor 88 and the new remainder 71,and apply the division lemma to get
88 = 71 x 1 + 17
We consider the new divisor 71 and the new remainder 17,and apply the division lemma to get
71 = 17 x 4 + 3
We consider the new divisor 17 and the new remainder 3,and apply the division lemma to get
17 = 3 x 5 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 653 and 406 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(71,17) = HCF(88,71) = HCF(159,88) = HCF(247,159) = HCF(406,247) = HCF(653,406) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 916 > 1, we apply the division lemma to 916 and 1, to get
916 = 1 x 916 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 916 is 1
Notice that 1 = HCF(916,1) .
