HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 357, 259 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 357, 259 is 7 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 357, 259 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 357, 259 is 7.
HCF(357, 259) = 7
HCF of 357, 259 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 357, 259 is 7.
Highest Common Factor of 357,259 is 7
Step 1: Since 357 > 259, we apply the division lemma to 357 and 259, to get
357 = 259 x 1 + 98
Step 2: Since the reminder 259 ≠ 0, we apply division lemma to 98 and 259, to get
259 = 98 x 2 + 63
Step 3: We consider the new divisor 98 and the new remainder 63, and apply the division lemma to get
98 = 63 x 1 + 35
We consider the new divisor 63 and the new remainder 35,and apply the division lemma to get
63 = 35 x 1 + 28
We consider the new divisor 35 and the new remainder 28,and apply the division lemma to get
35 = 28 x 1 + 7
We consider the new divisor 28 and the new remainder 7,and apply the division lemma to get
28 = 7 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 357 and 259 is 7
Notice that 7 = HCF(28,7) = HCF(35,28) = HCF(63,35) = HCF(98,63) = HCF(259,98) = HCF(357,259) .
