HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 832, 455 i.e. 13 the largest integer that leaves a remainder zero for all numbers.
HCF of 832, 455 is 13 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 832, 455 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 832, 455 is 13.
HCF(832, 455) = 13
HCF of 832, 455 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 832, 455 is 13.
Highest Common Factor of 832,455 is 13
Step 1: Since 832 > 455, we apply the division lemma to 832 and 455, to get
832 = 455 x 1 + 377
Step 2: Since the reminder 455 ≠ 0, we apply division lemma to 377 and 455, to get
455 = 377 x 1 + 78
Step 3: We consider the new divisor 377 and the new remainder 78, and apply the division lemma to get
377 = 78 x 4 + 65
We consider the new divisor 78 and the new remainder 65,and apply the division lemma to get
78 = 65 x 1 + 13
We consider the new divisor 65 and the new remainder 13,and apply the division lemma to get
65 = 13 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 832 and 455 is 13
Notice that 13 = HCF(65,13) = HCF(78,65) = HCF(377,78) = HCF(455,377) = HCF(832,455) .
