HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 649, 85723 i.e. 11 the largest integer that leaves a remainder zero for all numbers.
HCF of 649, 85723 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 649, 85723 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 649, 85723 is 11.
HCF(649, 85723) = 11
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 649, 85723 is 11.
Step 1: Since 85723 > 649, we apply the division lemma to 85723 and 649, to get
85723 = 649 x 132 + 55
Step 2: Since the reminder 649 ≠ 0, we apply division lemma to 55 and 649, to get
649 = 55 x 11 + 44
Step 3: We consider the new divisor 55 and the new remainder 44, and apply the division lemma to get
55 = 44 x 1 + 11
We consider the new divisor 44 and the new remainder 11, and apply the division lemma to get
44 = 11 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 649 and 85723 is 11
Notice that 11 = HCF(44,11) = HCF(55,44) = HCF(649,55) = HCF(85723,649) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
