HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 841, 987, 830 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 841, 987, 830 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 841, 987, 830 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 841, 987, 830 is 1.
HCF(841, 987, 830) = 1
HCF of 841, 987, 830 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 841, 987, 830 is 1.
Highest Common Factor of 841,987,830 is 1
Step 1: Since 987 > 841, we apply the division lemma to 987 and 841, to get
987 = 841 x 1 + 146
Step 2: Since the reminder 841 ≠ 0, we apply division lemma to 146 and 841, to get
841 = 146 x 5 + 111
Step 3: We consider the new divisor 146 and the new remainder 111, and apply the division lemma to get
146 = 111 x 1 + 35
We consider the new divisor 111 and the new remainder 35,and apply the division lemma to get
111 = 35 x 3 + 6
We consider the new divisor 35 and the new remainder 6,and apply the division lemma to get
35 = 6 x 5 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 841 and 987 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(35,6) = HCF(111,35) = HCF(146,111) = HCF(841,146) = HCF(987,841) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 830 > 1, we apply the division lemma to 830 and 1, to get
830 = 1 x 830 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 830 is 1
Notice that 1 = HCF(830,1) .
