HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 317, 654, 916, 556 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 317, 654, 916, 556 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 317, 654, 916, 556 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 317, 654, 916, 556 is 1.
HCF(317, 654, 916, 556) = 1
HCF of 317, 654, 916, 556 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 317, 654, 916, 556 is 1.
Highest Common Factor of 317,654,916,556 is 1
Step 1: Since 654 > 317, we apply the division lemma to 654 and 317, to get
654 = 317 x 2 + 20
Step 2: Since the reminder 317 ≠ 0, we apply division lemma to 20 and 317, to get
317 = 20 x 15 + 17
Step 3: We consider the new divisor 20 and the new remainder 17, and apply the division lemma to get
20 = 17 x 1 + 3
We consider the new divisor 17 and the new remainder 3,and apply the division lemma to get
17 = 3 x 5 + 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 317 and 654 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(20,17) = HCF(317,20) = HCF(654,317) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 916 > 1, we apply the division lemma to 916 and 1, to get
916 = 1 x 916 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 916 is 1
Notice that 1 = HCF(916,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 556 > 1, we apply the division lemma to 556 and 1, to get
556 = 1 x 556 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 556 is 1
Notice that 1 = HCF(556,1) .
