HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 359, 512, 686 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 359, 512, 686 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 359, 512, 686 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 359, 512, 686 is 1.
HCF(359, 512, 686) = 1
HCF of 359, 512, 686 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 359, 512, 686 is 1.
Highest Common Factor of 359,512,686 is 1
Step 1: Since 512 > 359, we apply the division lemma to 512 and 359, to get
512 = 359 x 1 + 153
Step 2: Since the reminder 359 ≠ 0, we apply division lemma to 153 and 359, to get
359 = 153 x 2 + 53
Step 3: We consider the new divisor 153 and the new remainder 53, and apply the division lemma to get
153 = 53 x 2 + 47
We consider the new divisor 53 and the new remainder 47,and apply the division lemma to get
53 = 47 x 1 + 6
We consider the new divisor 47 and the new remainder 6,and apply the division lemma to get
47 = 6 x 7 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 359 and 512 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(47,6) = HCF(53,47) = HCF(153,53) = HCF(359,153) = HCF(512,359) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 686 > 1, we apply the division lemma to 686 and 1, to get
686 = 1 x 686 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 686 is 1
Notice that 1 = HCF(686,1) .
