HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 447, 724, 979 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 447, 724, 979 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, 724, 979 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, 724, 979 is 1.

HCF(447, 724, 979) = 1

Highest common factor (HCF) of 447, 724, 979 is 1.

Highest Common Factor of 447,724,979 using Euclid's algorithm

Highest Common Factor of 447,724,979 is 1

Step 1: Since 724 > 447, we apply the division lemma to 724 and 447, to get

724 = 447 x 1 + 277

Step 2: Since the reminder 447 ≠ 0, we apply division lemma to 277 and 447, to get

447 = 277 x 1 + 170

Step 3: We consider the new divisor 277 and the new remainder 170, and apply the division lemma to get

277 = 170 x 1 + 107

We consider the new divisor 170 and the new remainder 107,and apply the division lemma to get

170 = 107 x 1 + 63

We consider the new divisor 107 and the new remainder 63,and apply the division lemma to get

107 = 63 x 1 + 44

We consider the new divisor 63 and the new remainder 44,and apply the division lemma to get

63 = 44 x 1 + 19

We consider the new divisor 44 and the new remainder 19,and apply the division lemma to get

44 = 19 x 2 + 6

We consider the new divisor 19 and the new remainder 6,and apply the division lemma to get

19 = 6 x 3 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 447 and 724 is 1

Notice that 1 = HCF(6,1) = HCF(19,6) = HCF(44,19) = HCF(63,44) = HCF(107,63) = HCF(170,107) = HCF(277,170) = HCF(447,277) = HCF(724,447) .

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

Step 1: Since 979 > 1, we apply the division lemma to 979 and 1, to get

979 = 1 x 979 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 979 is 1

Notice that 1 = HCF(979,1) .
