HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 538, 961 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 538, 961 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 538, 961 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 538, 961 is 1.
HCF(538, 961) = 1
HCF of 538, 961 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 538, 961 is 1.
Highest Common Factor of 538,961 is 1
Step 1: Since 961 > 538, we apply the division lemma to 961 and 538, to get
961 = 538 x 1 + 423
Step 2: Since the reminder 538 ≠ 0, we apply division lemma to 423 and 538, to get
538 = 423 x 1 + 115
Step 3: We consider the new divisor 423 and the new remainder 115, and apply the division lemma to get
423 = 115 x 3 + 78
We consider the new divisor 115 and the new remainder 78,and apply the division lemma to get
115 = 78 x 1 + 37
We consider the new divisor 78 and the new remainder 37,and apply the division lemma to get
78 = 37 x 2 + 4
We consider the new divisor 37 and the new remainder 4,and apply the division lemma to get
37 = 4 x 9 + 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 538 and 961 is 1
Notice that 1 = HCF(4,1) = HCF(37,4) = HCF(78,37) = HCF(115,78) = HCF(423,115) = HCF(538,423) = HCF(961,538) .
