HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 447, 619, 985 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 447, 619, 985 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 447, 619, 985 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 447, 619, 985 is 1.

HCF(447, 619, 985) = 1

HCF of 447, 619, 985 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 447, 619, 985 is 1.

Highest Common Factor of 447,619,985 using Euclid's algorithm

Highest Common Factor of 447,619,985 is 1

Step 1: Since 619 > 447, we apply the division lemma to 619 and 447, to get

619 = 447 x 1 + 172

Step 2: Since the reminder 447 ≠ 0, we apply division lemma to 172 and 447, to get

447 = 172 x 2 + 103

Step 3: We consider the new divisor 172 and the new remainder 103, and apply the division lemma to get

172 = 103 x 1 + 69

We consider the new divisor 103 and the new remainder 69,and apply the division lemma to get

103 = 69 x 1 + 34

We consider the new divisor 69 and the new remainder 34,and apply the division lemma to get

69 = 34 x 2 + 1

We consider the new divisor 34 and the new remainder 1,and apply the division lemma to get

34 = 1 x 34 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 447 and 619 is 1

Notice that 1 = HCF(34,1) = HCF(69,34) = HCF(103,69) = HCF(172,103) = HCF(447,172) = HCF(619,447) .

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

Step 1: Since 985 > 1, we apply the division lemma to 985 and 1, to get

985 = 1 x 985 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 985 is 1

Notice that 1 = HCF(985,1) .
