HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 501, 865 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 501, 865 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 501, 865 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 501, 865 is 1.
HCF(501, 865) = 1
HCF of 501, 865 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 501, 865 is 1.
Highest Common Factor of 501,865 is 1
Step 1: Since 865 > 501, we apply the division lemma to 865 and 501, to get
865 = 501 x 1 + 364
Step 2: Since the reminder 501 ≠ 0, we apply division lemma to 364 and 501, to get
501 = 364 x 1 + 137
Step 3: We consider the new divisor 364 and the new remainder 137, and apply the division lemma to get
364 = 137 x 2 + 90
We consider the new divisor 137 and the new remainder 90,and apply the division lemma to get
137 = 90 x 1 + 47
We consider the new divisor 90 and the new remainder 47,and apply the division lemma to get
90 = 47 x 1 + 43
We consider the new divisor 47 and the new remainder 43,and apply the division lemma to get
47 = 43 x 1 + 4
We consider the new divisor 43 and the new remainder 4,and apply the division lemma to get
43 = 4 x 10 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 501 and 865 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(43,4) = HCF(47,43) = HCF(90,47) = HCF(137,90) = HCF(364,137) = HCF(501,364) = HCF(865,501) .
