HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 380, 679 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 380, 679 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 380, 679 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 380, 679 is 1.
HCF(380, 679) = 1
HCF of 380, 679 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 380, 679 is 1.
Highest Common Factor of 380,679 is 1
Step 1: Since 679 > 380, we apply the division lemma to 679 and 380, to get
679 = 380 x 1 + 299
Step 2: Since the reminder 380 ≠ 0, we apply division lemma to 299 and 380, to get
380 = 299 x 1 + 81
Step 3: We consider the new divisor 299 and the new remainder 81, and apply the division lemma to get
299 = 81 x 3 + 56
We consider the new divisor 81 and the new remainder 56,and apply the division lemma to get
81 = 56 x 1 + 25
We consider the new divisor 56 and the new remainder 25,and apply the division lemma to get
56 = 25 x 2 + 6
We consider the new divisor 25 and the new remainder 6,and apply the division lemma to get
25 = 6 x 4 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 380 and 679 is 1
Notice that 1 = HCF(6,1) = HCF(25,6) = HCF(56,25) = HCF(81,56) = HCF(299,81) = HCF(380,299) = HCF(679,380) .
