HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 430, 725, 446 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 430, 725, 446 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 430, 725, 446 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 430, 725, 446 is 1.

HCF(430, 725, 446) = 1

Highest Common Factor of 430,725,446 using Euclid's algorithm

Highest Common Factor of 430,725,446 is 1

Step 1: Since 725 > 430, we apply the division lemma to 725 and 430, to get

725 = 430 x 1 + 295

Step 2: Since the reminder 430 ≠ 0, we apply division lemma to 295 and 430, to get

430 = 295 x 1 + 135

Step 3: We consider the new divisor 295 and the new remainder 135, and apply the division lemma to get

295 = 135 x 2 + 25

We consider the new divisor 135 and the new remainder 25,and apply the division lemma to get

135 = 25 x 5 + 10

We consider the new divisor 25 and the new remainder 10,and apply the division lemma to get

25 = 10 x 2 + 5

We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get

10 = 5 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 430 and 725 is 5

Notice that 5 = HCF(10,5) = HCF(25,10) = HCF(135,25) = HCF(295,135) = HCF(430,295) = HCF(725,430) .

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

Step 1: Since 446 > 5, we apply the division lemma to 446 and 5, to get

446 = 5 x 89 + 1

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 446 is 1

Notice that 1 = HCF(5,1) = HCF(446,5) .
