HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 409, 253 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 409, 253 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 409, 253 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 409, 253 is 1.
HCF(409, 253) = 1
HCF of 409, 253 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 409, 253 is 1.
Highest Common Factor of 409,253 is 1
Step 1: Since 409 > 253, we apply the division lemma to 409 and 253, to get
409 = 253 x 1 + 156
Step 2: Since the reminder 253 ≠ 0, we apply division lemma to 156 and 253, to get
253 = 156 x 1 + 97
Step 3: We consider the new divisor 156 and the new remainder 97, and apply the division lemma to get
156 = 97 x 1 + 59
We consider the new divisor 97 and the new remainder 59,and apply the division lemma to get
97 = 59 x 1 + 38
We consider the new divisor 59 and the new remainder 38,and apply the division lemma to get
59 = 38 x 1 + 21
We consider the new divisor 38 and the new remainder 21,and apply the division lemma to get
38 = 21 x 1 + 17
We consider the new divisor 21 and the new remainder 17,and apply the division lemma to get
21 = 17 x 1 + 4
We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get
17 = 4 x 4 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 409 and 253 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(21,17) = HCF(38,21) = HCF(59,38) = HCF(97,59) = HCF(156,97) = HCF(253,156) = HCF(409,253) .
