HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 701, 838, 189 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 701, 838, 189 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 701, 838, 189 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 701, 838, 189 is 1.
HCF(701, 838, 189) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 701, 838, 189 is 1.
Step 1: Since 838 > 701, we apply the division lemma to 838 and 701, to get
838 = 701 x 1 + 137
Step 2: Since the reminder 701 ≠ 0, we apply division lemma to 137 and 701, to get
701 = 137 x 5 + 16
Step 3: We consider the new divisor 137 and the new remainder 16, and apply the division lemma to get
137 = 16 x 8 + 9
We consider the new divisor 16 and the new remainder 9,and apply the division lemma to get
16 = 9 x 1 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 701 and 838 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(16,9) = HCF(137,16) = HCF(701,137) = HCF(838,701) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 189 > 1, we apply the division lemma to 189 and 1, to get
189 = 1 x 189 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 189 is 1
Notice that 1 = HCF(189,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
