HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 863, 501, 920 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 863, 501, 920 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 863, 501, 920 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 863, 501, 920 is 1.
HCF(863, 501, 920) = 1
HCF of 863, 501, 920 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 863, 501, 920 is 1.
Highest Common Factor of 863,501,920 is 1
Step 1: Since 863 > 501, we apply the division lemma to 863 and 501, to get
863 = 501 x 1 + 362
Step 2: Since the reminder 501 ≠ 0, we apply division lemma to 362 and 501, to get
501 = 362 x 1 + 139
Step 3: We consider the new divisor 362 and the new remainder 139, and apply the division lemma to get
362 = 139 x 2 + 84
We consider the new divisor 139 and the new remainder 84,and apply the division lemma to get
139 = 84 x 1 + 55
We consider the new divisor 84 and the new remainder 55,and apply the division lemma to get
84 = 55 x 1 + 29
We consider the new divisor 55 and the new remainder 29,and apply the division lemma to get
55 = 29 x 1 + 26
We consider the new divisor 29 and the new remainder 26,and apply the division lemma to get
29 = 26 x 1 + 3
We consider the new divisor 26 and the new remainder 3,and apply the division lemma to get
26 = 3 x 8 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 863 and 501 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(26,3) = HCF(29,26) = HCF(55,29) = HCF(84,55) = HCF(139,84) = HCF(362,139) = HCF(501,362) = HCF(863,501) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 920 > 1, we apply the division lemma to 920 and 1, to get
920 = 1 x 920 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 920 is 1
Notice that 1 = HCF(920,1) .
