HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 825, 312, 698 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 825, 312, 698 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, 312, 698 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, 312, 698 is 1.
HCF(825, 312, 698) = 1
HCF of 825, 312, 698 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, 312, 698 is 1.
Highest Common Factor of 825,312,698 is 1
Step 1: Since 825 > 312, we apply the division lemma to 825 and 312, to get
825 = 312 x 2 + 201
Step 2: Since the reminder 312 ≠ 0, we apply division lemma to 201 and 312, to get
312 = 201 x 1 + 111
Step 3: We consider the new divisor 201 and the new remainder 111, and apply the division lemma to get
201 = 111 x 1 + 90
We consider the new divisor 111 and the new remainder 90,and apply the division lemma to get
111 = 90 x 1 + 21
We consider the new divisor 90 and the new remainder 21,and apply the division lemma to get
90 = 21 x 4 + 6
We consider the new divisor 21 and the new remainder 6,and apply the division lemma to get
21 = 6 x 3 + 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 825 and 312 is 3
Notice that 3 = HCF(6,3) = HCF(21,6) = HCF(90,21) = HCF(111,90) = HCF(201,111) = HCF(312,201) = HCF(825,312) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 698 > 3, we apply the division lemma to 698 and 3, to get
698 = 3 x 232 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 698 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(698,3) .
