HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 259, 690 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 259, 690 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 259, 690 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 259, 690 is 1.
HCF(259, 690) = 1
HCF of 259, 690 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 259, 690 is 1.
Highest Common Factor of 259,690 is 1
Step 1: Since 690 > 259, we apply the division lemma to 690 and 259, to get
690 = 259 x 2 + 172
Step 2: Since the reminder 259 ≠ 0, we apply division lemma to 172 and 259, to get
259 = 172 x 1 + 87
Step 3: We consider the new divisor 172 and the new remainder 87, and apply the division lemma to get
172 = 87 x 1 + 85
We consider the new divisor 87 and the new remainder 85,and apply the division lemma to get
87 = 85 x 1 + 2
We consider the new divisor 85 and the new remainder 2,and apply the division lemma to get
85 = 2 x 42 + 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 259 and 690 is 1
Notice that 1 = HCF(2,1) = HCF(85,2) = HCF(87,85) = HCF(172,87) = HCF(259,172) = HCF(690,259) .
