HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 476, 289, 505 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 476, 289, 505 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, 289, 505 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, 289, 505 is 1.
HCF(476, 289, 505) = 1
HCF of 476, 289, 505 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, 289, 505 is 1.
Highest Common Factor of 476,289,505 is 1
Step 1: Since 476 > 289, we apply the division lemma to 476 and 289, to get
476 = 289 x 1 + 187
Step 2: Since the reminder 289 ≠ 0, we apply division lemma to 187 and 289, to get
289 = 187 x 1 + 102
Step 3: We consider the new divisor 187 and the new remainder 102, and apply the division lemma to get
187 = 102 x 1 + 85
We consider the new divisor 102 and the new remainder 85,and apply the division lemma to get
102 = 85 x 1 + 17
We consider the new divisor 85 and the new remainder 17,and apply the division lemma to get
85 = 17 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 476 and 289 is 17
Notice that 17 = HCF(85,17) = HCF(102,85) = HCF(187,102) = HCF(289,187) = HCF(476,289) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 505 > 17, we apply the division lemma to 505 and 17, to get
505 = 17 x 29 + 12
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 12 and 17, to get
17 = 12 x 1 + 5
Step 3: We consider the new divisor 12 and the new remainder 5, and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 17 and 505 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(17,12) = HCF(505,17) .
