HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 447, 709, 790 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 447, 709, 790 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, 709, 790 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, 709, 790 is 1.

HCF(447, 709, 790) = 1

HCF of 447, 709, 790 using Euclid's algorithm

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

Highest common factor (HCF) of 447, 709, 790 is 1.

Highest Common Factor of 447,709,790 using Euclid's algorithm

Highest Common Factor of 447,709,790 is 1

Step 1: Since 709 > 447, we apply the division lemma to 709 and 447, to get

709 = 447 x 1 + 262

Step 2: Since the reminder 447 ≠ 0, we apply division lemma to 262 and 447, to get

447 = 262 x 1 + 185

Step 3: We consider the new divisor 262 and the new remainder 185, and apply the division lemma to get

262 = 185 x 1 + 77

We consider the new divisor 185 and the new remainder 77,and apply the division lemma to get

185 = 77 x 2 + 31

We consider the new divisor 77 and the new remainder 31,and apply the division lemma to get

77 = 31 x 2 + 15

We consider the new divisor 31 and the new remainder 15,and apply the division lemma to get

31 = 15 x 2 + 1

We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get

15 = 1 x 15 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 447 and 709 is 1

Notice that 1 = HCF(15,1) = HCF(31,15) = HCF(77,31) = HCF(185,77) = HCF(262,185) = HCF(447,262) = HCF(709,447) .

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

Step 1: Since 790 > 1, we apply the division lemma to 790 and 1, to get

790 = 1 x 790 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 790 is 1

Notice that 1 = HCF(790,1) .
