HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 284, 870, 53 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 284, 870, 53 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 284, 870, 53 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 284, 870, 53 is 1.
HCF(284, 870, 53) = 1
HCF of 284, 870, 53 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 284, 870, 53 is 1.
Highest Common Factor of 284,870,53 is 1
Step 1: Since 870 > 284, we apply the division lemma to 870 and 284, to get
870 = 284 x 3 + 18
Step 2: Since the reminder 284 ≠ 0, we apply division lemma to 18 and 284, to get
284 = 18 x 15 + 14
Step 3: We consider the new divisor 18 and the new remainder 14, and apply the division lemma to get
18 = 14 x 1 + 4
We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get
14 = 4 x 3 + 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 284 and 870 is 2
Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(18,14) = HCF(284,18) = HCF(870,284) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 53 > 2, we apply the division lemma to 53 and 2, to get
53 = 2 x 26 + 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 53 is 1
Notice that 1 = HCF(2,1) = HCF(53,2) .
