HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 858, 484, 502, 819 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 858, 484, 502, 819 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 858, 484, 502, 819 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 858, 484, 502, 819 is 1.
HCF(858, 484, 502, 819) = 1
HCF of 858, 484, 502, 819 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 858, 484, 502, 819 is 1.
Highest Common Factor of 858,484,502,819 is 1
Step 1: Since 858 > 484, we apply the division lemma to 858 and 484, to get
858 = 484 x 1 + 374
Step 2: Since the reminder 484 ≠ 0, we apply division lemma to 374 and 484, to get
484 = 374 x 1 + 110
Step 3: We consider the new divisor 374 and the new remainder 110, and apply the division lemma to get
374 = 110 x 3 + 44
We consider the new divisor 110 and the new remainder 44,and apply the division lemma to get
110 = 44 x 2 + 22
We consider the new divisor 44 and the new remainder 22,and apply the division lemma to get
44 = 22 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 22, the HCF of 858 and 484 is 22
Notice that 22 = HCF(44,22) = HCF(110,44) = HCF(374,110) = HCF(484,374) = HCF(858,484) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 502 > 22, we apply the division lemma to 502 and 22, to get
502 = 22 x 22 + 18
Step 2: Since the reminder 22 ≠ 0, we apply division lemma to 18 and 22, to get
22 = 18 x 1 + 4
Step 3: We consider the new divisor 18 and the new remainder 4, and apply the division lemma to get
18 = 4 x 4 + 2
We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 22 and 502 is 2
Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(22,18) = HCF(502,22) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 819 > 2, we apply the division lemma to 819 and 2, to get
819 = 2 x 409 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 819 is 1
Notice that 1 = HCF(2,1) = HCF(819,2) .
