HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 680, 951 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 680, 951 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 680, 951 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 680, 951 is 1.
HCF(680, 951) = 1
HCF of 680, 951 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 680, 951 is 1.
Highest Common Factor of 680,951 is 1
Step 1: Since 951 > 680, we apply the division lemma to 951 and 680, to get
951 = 680 x 1 + 271
Step 2: Since the reminder 680 ≠ 0, we apply division lemma to 271 and 680, to get
680 = 271 x 2 + 138
Step 3: We consider the new divisor 271 and the new remainder 138, and apply the division lemma to get
271 = 138 x 1 + 133
We consider the new divisor 138 and the new remainder 133,and apply the division lemma to get
138 = 133 x 1 + 5
We consider the new divisor 133 and the new remainder 5,and apply the division lemma to get
133 = 5 x 26 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 680 and 951 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(133,5) = HCF(138,133) = HCF(271,138) = HCF(680,271) = HCF(951,680) .
