HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 115, 111, 669 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 115, 111, 669 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 115, 111, 669 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 115, 111, 669 is 1.
HCF(115, 111, 669) = 1
HCF of 115, 111, 669 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 115, 111, 669 is 1.
Highest Common Factor of 115,111,669 is 1
Step 1: Since 115 > 111, we apply the division lemma to 115 and 111, to get
115 = 111 x 1 + 4
Step 2: Since the reminder 111 ≠ 0, we apply division lemma to 4 and 111, to get
111 = 4 x 27 + 3
Step 3: We consider the new divisor 4 and the new remainder 3, and apply the division lemma to get
4 = 3 x 1 + 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 115 and 111 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(111,4) = HCF(115,111) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 669 > 1, we apply the division lemma to 669 and 1, to get
669 = 1 x 669 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 669 is 1
Notice that 1 = HCF(669,1) .
