HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 825, 3938, 6993 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 825, 3938, 6993 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 825, 3938, 6993 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 825, 3938, 6993 is 1.
HCF(825, 3938, 6993) = 1
HCF of 825, 3938, 6993 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 825, 3938, 6993 is 1.
Highest Common Factor of 825,3938,6993 is 1
Step 1: Since 3938 > 825, we apply the division lemma to 3938 and 825, to get
3938 = 825 x 4 + 638
Step 2: Since the reminder 825 ≠ 0, we apply division lemma to 638 and 825, to get
825 = 638 x 1 + 187
Step 3: We consider the new divisor 638 and the new remainder 187, and apply the division lemma to get
638 = 187 x 3 + 77
We consider the new divisor 187 and the new remainder 77,and apply the division lemma to get
187 = 77 x 2 + 33
We consider the new divisor 77 and the new remainder 33,and apply the division lemma to get
77 = 33 x 2 + 11
We consider the new divisor 33 and the new remainder 11,and apply the division lemma to get
33 = 11 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 825 and 3938 is 11
Notice that 11 = HCF(33,11) = HCF(77,33) = HCF(187,77) = HCF(638,187) = HCF(825,638) = HCF(3938,825) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 6993 > 11, we apply the division lemma to 6993 and 11, to get
6993 = 11 x 635 + 8
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 8 and 11, to get
11 = 8 x 1 + 3
Step 3: We consider the new divisor 8 and the new remainder 3, and apply the division lemma to get
8 = 3 x 2 + 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 11 and 6993 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(6993,11) .
