HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 785, 1185, 8804 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 785, 1185, 8804 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 785, 1185, 8804 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 785, 1185, 8804 is 1.
HCF(785, 1185, 8804) = 1
HCF of 785, 1185, 8804 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 785, 1185, 8804 is 1.
Highest Common Factor of 785,1185,8804 is 1
Step 1: Since 1185 > 785, we apply the division lemma to 1185 and 785, to get
1185 = 785 x 1 + 400
Step 2: Since the reminder 785 ≠ 0, we apply division lemma to 400 and 785, to get
785 = 400 x 1 + 385
Step 3: We consider the new divisor 400 and the new remainder 385, and apply the division lemma to get
400 = 385 x 1 + 15
We consider the new divisor 385 and the new remainder 15,and apply the division lemma to get
385 = 15 x 25 + 10
We consider the new divisor 15 and the new remainder 10,and apply the division lemma to get
15 = 10 x 1 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 785 and 1185 is 5
Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(385,15) = HCF(400,385) = HCF(785,400) = HCF(1185,785) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 8804 > 5, we apply the division lemma to 8804 and 5, to get
8804 = 5 x 1760 + 4
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get
5 = 4 x 1 + 1
Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 8804 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(8804,5) .
