HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 404, 920, 247 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 404, 920, 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 404, 920, 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 404, 920, 247 is 1.
HCF(404, 920, 247) = 1
HCF of 404, 920, 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 404, 920, 247 is 1.
Highest Common Factor of 404,920,247 is 1
Step 1: Since 920 > 404, we apply the division lemma to 920 and 404, to get
920 = 404 x 2 + 112
Step 2: Since the reminder 404 ≠ 0, we apply division lemma to 112 and 404, to get
404 = 112 x 3 + 68
Step 3: We consider the new divisor 112 and the new remainder 68, and apply the division lemma to get
112 = 68 x 1 + 44
We consider the new divisor 68 and the new remainder 44,and apply the division lemma to get
68 = 44 x 1 + 24
We consider the new divisor 44 and the new remainder 24,and apply the division lemma to get
44 = 24 x 1 + 20
We consider the new divisor 24 and the new remainder 20,and apply the division lemma to get
24 = 20 x 1 + 4
We consider the new divisor 20 and the new remainder 4,and apply the division lemma to get
20 = 4 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 404 and 920 is 4
Notice that 4 = HCF(20,4) = HCF(24,20) = HCF(44,24) = HCF(68,44) = HCF(112,68) = HCF(404,112) = HCF(920,404) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 247 > 4, we apply the division lemma to 247 and 4, to get
247 = 4 x 61 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 247 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(247,4) .
