HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 476, 560, 247 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 476, 560, 247 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 476, 560, 247 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 476, 560, 247 is 1.
HCF(476, 560, 247) = 1
HCF of 476, 560, 247 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 476, 560, 247 is 1.
Highest Common Factor of 476,560,247 is 1
Step 1: Since 560 > 476, we apply the division lemma to 560 and 476, to get
560 = 476 x 1 + 84
Step 2: Since the reminder 476 ≠ 0, we apply division lemma to 84 and 476, to get
476 = 84 x 5 + 56
Step 3: We consider the new divisor 84 and the new remainder 56, and apply the division lemma to get
84 = 56 x 1 + 28
We consider the new divisor 56 and the new remainder 28, and apply the division lemma to get
56 = 28 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 28, the HCF of 476 and 560 is 28
Notice that 28 = HCF(56,28) = HCF(84,56) = HCF(476,84) = HCF(560,476) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 247 > 28, we apply the division lemma to 247 and 28, to get
247 = 28 x 8 + 23
Step 2: Since the reminder 28 ≠ 0, we apply division lemma to 23 and 28, to get
28 = 23 x 1 + 5
Step 3: We consider the new divisor 23 and the new remainder 5, and apply the division lemma to get
23 = 5 x 4 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 28 and 247 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(23,5) = HCF(28,23) = HCF(247,28) .
