HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 662, 1111, 5561 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 662, 1111, 5561 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 662, 1111, 5561 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 662, 1111, 5561 is 1.
HCF(662, 1111, 5561) = 1
HCF of 662, 1111, 5561 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 662, 1111, 5561 is 1.
Highest Common Factor of 662,1111,5561 is 1
Step 1: Since 1111 > 662, we apply the division lemma to 1111 and 662, to get
1111 = 662 x 1 + 449
Step 2: Since the reminder 662 ≠ 0, we apply division lemma to 449 and 662, to get
662 = 449 x 1 + 213
Step 3: We consider the new divisor 449 and the new remainder 213, and apply the division lemma to get
449 = 213 x 2 + 23
We consider the new divisor 213 and the new remainder 23,and apply the division lemma to get
213 = 23 x 9 + 6
We consider the new divisor 23 and the new remainder 6,and apply the division lemma to get
23 = 6 x 3 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 662 and 1111 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(23,6) = HCF(213,23) = HCF(449,213) = HCF(662,449) = HCF(1111,662) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 5561 > 1, we apply the division lemma to 5561 and 1, to get
5561 = 1 x 5561 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 5561 is 1
Notice that 1 = HCF(5561,1) .
