HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 259, 656 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 259, 656 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, 656 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, 656 is 1.
HCF(259, 656) = 1
HCF of 259, 656 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, 656 is 1.
Highest Common Factor of 259,656 is 1
Step 1: Since 656 > 259, we apply the division lemma to 656 and 259, to get
656 = 259 x 2 + 138
Step 2: Since the reminder 259 ≠ 0, we apply division lemma to 138 and 259, to get
259 = 138 x 1 + 121
Step 3: We consider the new divisor 138 and the new remainder 121, and apply the division lemma to get
138 = 121 x 1 + 17
We consider the new divisor 121 and the new remainder 17,and apply the division lemma to get
121 = 17 x 7 + 2
We consider the new divisor 17 and the new remainder 2,and apply the division lemma to get
17 = 2 x 8 + 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 656 is 1
Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(121,17) = HCF(138,121) = HCF(259,138) = HCF(656,259) .
