HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 738, 447 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 738, 447 is 3 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 738, 447 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 738, 447 is 3.

HCF(738, 447) = 3

Highest common factor (HCF) of 738, 447 is 3.

Highest Common Factor of 738,447 using Euclid's algorithm

Highest Common Factor of 738,447 is 3

Step 1: Since 738 > 447, we apply the division lemma to 738 and 447, to get

738 = 447 x 1 + 291

Step 2: Since the reminder 447 ≠ 0, we apply division lemma to 291 and 447, to get

447 = 291 x 1 + 156

Step 3: We consider the new divisor 291 and the new remainder 156, and apply the division lemma to get

291 = 156 x 1 + 135

We consider the new divisor 156 and the new remainder 135,and apply the division lemma to get

156 = 135 x 1 + 21

We consider the new divisor 135 and the new remainder 21,and apply the division lemma to get

135 = 21 x 6 + 9

We consider the new divisor 21 and the new remainder 9,and apply the division lemma to get

21 = 9 x 2 + 3

We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get

9 = 3 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 738 and 447 is 3

Notice that 3 = HCF(9,3) = HCF(21,9) = HCF(135,21) = HCF(156,135) = HCF(291,156) = HCF(447,291) = HCF(738,447) .
