HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 166, 4747 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 166, 4747 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 166, 4747 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 166, 4747 is 1.
HCF(166, 4747) = 1
HCF of 166, 4747 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 166, 4747 is 1.
Highest Common Factor of 166,4747 is 1
Step 1: Since 4747 > 166, we apply the division lemma to 4747 and 166, to get
4747 = 166 x 28 + 99
Step 2: Since the reminder 166 ≠ 0, we apply division lemma to 99 and 166, to get
166 = 99 x 1 + 67
Step 3: We consider the new divisor 99 and the new remainder 67, and apply the division lemma to get
99 = 67 x 1 + 32
We consider the new divisor 67 and the new remainder 32,and apply the division lemma to get
67 = 32 x 2 + 3
We consider the new divisor 32 and the new remainder 3,and apply the division lemma to get
32 = 3 x 10 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 166 and 4747 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(32,3) = HCF(67,32) = HCF(99,67) = HCF(166,99) = HCF(4747,166) .
