HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 498, 285, 30, 884 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 498, 285, 30, 884 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 498, 285, 30, 884 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 498, 285, 30, 884 is 1.
HCF(498, 285, 30, 884) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 498, 285, 30, 884 is 1.
Step 1: Since 498 > 285, we apply the division lemma to 498 and 285, to get
498 = 285 x 1 + 213
Step 2: Since the reminder 285 ≠ 0, we apply division lemma to 213 and 285, to get
285 = 213 x 1 + 72
Step 3: We consider the new divisor 213 and the new remainder 72, and apply the division lemma to get
213 = 72 x 2 + 69
We consider the new divisor 72 and the new remainder 69,and apply the division lemma to get
72 = 69 x 1 + 3
We consider the new divisor 69 and the new remainder 3,and apply the division lemma to get
69 = 3 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 498 and 285 is 3
Notice that 3 = HCF(69,3) = HCF(72,69) = HCF(213,72) = HCF(285,213) = HCF(498,285) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 30 > 3, we apply the division lemma to 30 and 3, to get
30 = 3 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 30 is 3
Notice that 3 = HCF(30,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 884 > 3, we apply the division lemma to 884 and 3, to get
884 = 3 x 294 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 884 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(884,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
