HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 858, 4961 i.e. 11 the largest integer that leaves a remainder zero for all numbers.
HCF of 858, 4961 is 11 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 858, 4961 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 858, 4961 is 11.
HCF(858, 4961) = 11
HCF of 858, 4961 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 858, 4961 is 11.
Highest Common Factor of 858,4961 is 11
Step 1: Since 4961 > 858, we apply the division lemma to 4961 and 858, to get
4961 = 858 x 5 + 671
Step 2: Since the reminder 858 ≠ 0, we apply division lemma to 671 and 858, to get
858 = 671 x 1 + 187
Step 3: We consider the new divisor 671 and the new remainder 187, and apply the division lemma to get
671 = 187 x 3 + 110
We consider the new divisor 187 and the new remainder 110,and apply the division lemma to get
187 = 110 x 1 + 77
We consider the new divisor 110 and the new remainder 77,and apply the division lemma to get
110 = 77 x 1 + 33
We consider the new divisor 77 and the new remainder 33,and apply the division lemma to get
77 = 33 x 2 + 11
We consider the new divisor 33 and the new remainder 11,and apply the division lemma to get
33 = 11 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 858 and 4961 is 11
Notice that 11 = HCF(33,11) = HCF(77,33) = HCF(110,77) = HCF(187,110) = HCF(671,187) = HCF(858,671) = HCF(4961,858) .
