HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 251, 667, 724 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 251, 667, 724 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 251, 667, 724 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 251, 667, 724 is 1.
HCF(251, 667, 724) = 1
HCF of 251, 667, 724 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 251, 667, 724 is 1.
Highest Common Factor of 251,667,724 is 1
Step 1: Since 667 > 251, we apply the division lemma to 667 and 251, to get
667 = 251 x 2 + 165
Step 2: Since the reminder 251 ≠ 0, we apply division lemma to 165 and 251, to get
251 = 165 x 1 + 86
Step 3: We consider the new divisor 165 and the new remainder 86, and apply the division lemma to get
165 = 86 x 1 + 79
We consider the new divisor 86 and the new remainder 79,and apply the division lemma to get
86 = 79 x 1 + 7
We consider the new divisor 79 and the new remainder 7,and apply the division lemma to get
79 = 7 x 11 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 251 and 667 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(79,7) = HCF(86,79) = HCF(165,86) = HCF(251,165) = HCF(667,251) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 724 > 1, we apply the division lemma to 724 and 1, to get
724 = 1 x 724 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 724 is 1
Notice that 1 = HCF(724,1) .
