HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 803, 687, 524 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 803, 687, 524 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 803, 687, 524 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 803, 687, 524 is 1.
HCF(803, 687, 524) = 1
HCF of 803, 687, 524 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 803, 687, 524 is 1.
Highest Common Factor of 803,687,524 is 1
Step 1: Since 803 > 687, we apply the division lemma to 803 and 687, to get
803 = 687 x 1 + 116
Step 2: Since the reminder 687 ≠ 0, we apply division lemma to 116 and 687, to get
687 = 116 x 5 + 107
Step 3: We consider the new divisor 116 and the new remainder 107, and apply the division lemma to get
116 = 107 x 1 + 9
We consider the new divisor 107 and the new remainder 9,and apply the division lemma to get
107 = 9 x 11 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 803 and 687 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(107,9) = HCF(116,107) = HCF(687,116) = HCF(803,687) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 524 > 1, we apply the division lemma to 524 and 1, to get
524 = 1 x 524 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 524 is 1
Notice that 1 = HCF(524,1) .
