HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 4561, 4160, 70740 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 4561, 4160, 70740 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 4561, 4160, 70740 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 4561, 4160, 70740 is 1.

HCF(4561, 4160, 70740) = 1

HCF of 4561, 4160, 70740 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 4561, 4160, 70740 is 1.

Highest Common Factor of 4561,4160,70740 using Euclid's algorithm

Highest Common Factor of 4561,4160,70740 is 1

Step 1: Since 4561 > 4160, we apply the division lemma to 4561 and 4160, to get

4561 = 4160 x 1 + 401

Step 2: Since the reminder 4160 ≠ 0, we apply division lemma to 401 and 4160, to get

4160 = 401 x 10 + 150

Step 3: We consider the new divisor 401 and the new remainder 150, and apply the division lemma to get

401 = 150 x 2 + 101

We consider the new divisor 150 and the new remainder 101,and apply the division lemma to get

150 = 101 x 1 + 49

We consider the new divisor 101 and the new remainder 49,and apply the division lemma to get

101 = 49 x 2 + 3

We consider the new divisor 49 and the new remainder 3,and apply the division lemma to get

49 = 3 x 16 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4561 and 4160 is 1

Notice that 1 = HCF(3,1) = HCF(49,3) = HCF(101,49) = HCF(150,101) = HCF(401,150) = HCF(4160,401) = HCF(4561,4160) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 70740 > 1, we apply the division lemma to 70740 and 1, to get

70740 = 1 x 70740 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 70740 is 1

Notice that 1 = HCF(70740,1) .
