HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 651, 719 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 651, 719 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 651, 719 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 651, 719 is 1.
HCF(651, 719) = 1
HCF of 651, 719 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 651, 719 is 1.
Highest Common Factor of 651,719 is 1
Step 1: Since 719 > 651, we apply the division lemma to 719 and 651, to get
719 = 651 x 1 + 68
Step 2: Since the reminder 651 ≠ 0, we apply division lemma to 68 and 651, to get
651 = 68 x 9 + 39
Step 3: We consider the new divisor 68 and the new remainder 39, and apply the division lemma to get
68 = 39 x 1 + 29
We consider the new divisor 39 and the new remainder 29,and apply the division lemma to get
39 = 29 x 1 + 10
We consider the new divisor 29 and the new remainder 10,and apply the division lemma to get
29 = 10 x 2 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 651 and 719 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(29,10) = HCF(39,29) = HCF(68,39) = HCF(651,68) = HCF(719,651) .
