HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 687, 893, 559 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 687, 893, 559 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 687, 893, 559 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 687, 893, 559 is 1.
HCF(687, 893, 559) = 1
HCF of 687, 893, 559 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 687, 893, 559 is 1.
Highest Common Factor of 687,893,559 is 1
Step 1: Since 893 > 687, we apply the division lemma to 893 and 687, to get
893 = 687 x 1 + 206
Step 2: Since the reminder 687 ≠ 0, we apply division lemma to 206 and 687, to get
687 = 206 x 3 + 69
Step 3: We consider the new divisor 206 and the new remainder 69, and apply the division lemma to get
206 = 69 x 2 + 68
We consider the new divisor 69 and the new remainder 68,and apply the division lemma to get
69 = 68 x 1 + 1
We consider the new divisor 68 and the new remainder 1,and apply the division lemma to get
68 = 1 x 68 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 687 and 893 is 1
Notice that 1 = HCF(68,1) = HCF(69,68) = HCF(206,69) = HCF(687,206) = HCF(893,687) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 559 > 1, we apply the division lemma to 559 and 1, to get
559 = 1 x 559 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 559 is 1
Notice that 1 = HCF(559,1) .
