HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 925, 81355 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 925, 81355 is 5 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 925, 81355 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 925, 81355 is 5.
HCF(925, 81355) = 5
HCF of 925, 81355 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 925, 81355 is 5.
Highest Common Factor of 925,81355 is 5
Step 1: Since 81355 > 925, we apply the division lemma to 81355 and 925, to get
81355 = 925 x 87 + 880
Step 2: Since the reminder 925 ≠ 0, we apply division lemma to 880 and 925, to get
925 = 880 x 1 + 45
Step 3: We consider the new divisor 880 and the new remainder 45, and apply the division lemma to get
880 = 45 x 19 + 25
We consider the new divisor 45 and the new remainder 25,and apply the division lemma to get
45 = 25 x 1 + 20
We consider the new divisor 25 and the new remainder 20,and apply the division lemma to get
25 = 20 x 1 + 5
We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 925 and 81355 is 5
Notice that 5 = HCF(20,5) = HCF(25,20) = HCF(45,25) = HCF(880,45) = HCF(925,880) = HCF(81355,925) .
