HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 687, 993, 61, 838 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 687, 993, 61, 838 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, 993, 61, 838 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, 993, 61, 838 is 1.
HCF(687, 993, 61, 838) = 1
HCF of 687, 993, 61, 838 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, 993, 61, 838 is 1.
Highest Common Factor of 687,993,61,838 is 1
Step 1: Since 993 > 687, we apply the division lemma to 993 and 687, to get
993 = 687 x 1 + 306
Step 2: Since the reminder 687 ≠ 0, we apply division lemma to 306 and 687, to get
687 = 306 x 2 + 75
Step 3: We consider the new divisor 306 and the new remainder 75, and apply the division lemma to get
306 = 75 x 4 + 6
We consider the new divisor 75 and the new remainder 6,and apply the division lemma to get
75 = 6 x 12 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 687 and 993 is 3
Notice that 3 = HCF(6,3) = HCF(75,6) = HCF(306,75) = HCF(687,306) = HCF(993,687) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 61 > 3, we apply the division lemma to 61 and 3, to get
61 = 3 x 20 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 61 is 1
Notice that 1 = HCF(3,1) = HCF(61,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 838 > 1, we apply the division lemma to 838 and 1, to get
838 = 1 x 838 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 838 is 1
Notice that 1 = HCF(838,1) .
