HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 487, 549, 879, 811 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 487, 549, 879, 811 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 487, 549, 879, 811 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 487, 549, 879, 811 is 1.
HCF(487, 549, 879, 811) = 1
HCF of 487, 549, 879, 811 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 487, 549, 879, 811 is 1.
Highest Common Factor of 487,549,879,811 is 1
Step 1: Since 549 > 487, we apply the division lemma to 549 and 487, to get
549 = 487 x 1 + 62
Step 2: Since the reminder 487 ≠ 0, we apply division lemma to 62 and 487, to get
487 = 62 x 7 + 53
Step 3: We consider the new divisor 62 and the new remainder 53, and apply the division lemma to get
62 = 53 x 1 + 9
We consider the new divisor 53 and the new remainder 9,and apply the division lemma to get
53 = 9 x 5 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 487 and 549 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(53,9) = HCF(62,53) = HCF(487,62) = HCF(549,487) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 879 > 1, we apply the division lemma to 879 and 1, to get
879 = 1 x 879 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 879 is 1
Notice that 1 = HCF(879,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 811 > 1, we apply the division lemma to 811 and 1, to get
811 = 1 x 811 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 811 is 1
Notice that 1 = HCF(811,1) .
