HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 612, 841 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 870, 612, 841 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 870, 612, 841 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 870, 612, 841 is 1.
HCF(870, 612, 841) = 1
HCF of 870, 612, 841 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 870, 612, 841 is 1.
Highest Common Factor of 870,612,841 is 1
Step 1: Since 870 > 612, we apply the division lemma to 870 and 612, to get
870 = 612 x 1 + 258
Step 2: Since the reminder 612 ≠ 0, we apply division lemma to 258 and 612, to get
612 = 258 x 2 + 96
Step 3: We consider the new divisor 258 and the new remainder 96, and apply the division lemma to get
258 = 96 x 2 + 66
We consider the new divisor 96 and the new remainder 66,and apply the division lemma to get
96 = 66 x 1 + 30
We consider the new divisor 66 and the new remainder 30,and apply the division lemma to get
66 = 30 x 2 + 6
We consider the new divisor 30 and the new remainder 6,and apply the division lemma to get
30 = 6 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 870 and 612 is 6
Notice that 6 = HCF(30,6) = HCF(66,30) = HCF(96,66) = HCF(258,96) = HCF(612,258) = HCF(870,612) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 841 > 6, we apply the division lemma to 841 and 6, to get
841 = 6 x 140 + 1
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 1 and 6, to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6 and 841 is 1
Notice that 1 = HCF(6,1) = HCF(841,6) .
