HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 447, 620, 735 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 447, 620, 735 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, 620, 735 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, 620, 735 is 1.

HCF(447, 620, 735) = 1

Highest Common Factor of 447,620,735 using Euclid's algorithm

Highest Common Factor of 447,620,735 is 1

Step 1: Since 620 > 447, we apply the division lemma to 620 and 447, to get

620 = 447 x 1 + 173

Step 2: Since the reminder 447 ≠ 0, we apply division lemma to 173 and 447, to get

447 = 173 x 2 + 101

Step 3: We consider the new divisor 173 and the new remainder 101, and apply the division lemma to get

173 = 101 x 1 + 72

We consider the new divisor 101 and the new remainder 72,and apply the division lemma to get

101 = 72 x 1 + 29

We consider the new divisor 72 and the new remainder 29,and apply the division lemma to get

72 = 29 x 2 + 14

We consider the new divisor 29 and the new remainder 14,and apply the division lemma to get

29 = 14 x 2 + 1

We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get

14 = 1 x 14 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 447 and 620 is 1

Notice that 1 = HCF(14,1) = HCF(29,14) = HCF(72,29) = HCF(101,72) = HCF(173,101) = HCF(447,173) = HCF(620,447) .

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

Step 1: Since 735 > 1, we apply the division lemma to 735 and 1, to get

735 = 1 x 735 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 735 is 1

Notice that 1 = HCF(735,1) .
