HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 425, 685, 94, 872 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 425, 685, 94, 872 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 425, 685, 94, 872 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 425, 685, 94, 872 is 1.

HCF(425, 685, 94, 872) = 1

Highest common factor (HCF) of 425, 685, 94, 872 is 1.

Highest Common Factor of 425,685,94,872 using Euclid's algorithm

Highest Common Factor of 425,685,94,872 is 1

Step 1: Since 685 > 425, we apply the division lemma to 685 and 425, to get

685 = 425 x 1 + 260

Step 2: Since the reminder 425 ≠ 0, we apply division lemma to 260 and 425, to get

425 = 260 x 1 + 165

Step 3: We consider the new divisor 260 and the new remainder 165, and apply the division lemma to get

260 = 165 x 1 + 95

We consider the new divisor 165 and the new remainder 95,and apply the division lemma to get

165 = 95 x 1 + 70

We consider the new divisor 95 and the new remainder 70,and apply the division lemma to get

95 = 70 x 1 + 25

We consider the new divisor 70 and the new remainder 25,and apply the division lemma to get

70 = 25 x 2 + 20

We consider the new divisor 25 and the new remainder 20,and apply the division lemma to get

25 = 20 x 1 + 5

We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get

20 = 5 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 425 and 685 is 5

Notice that 5 = HCF(20,5) = HCF(25,20) = HCF(70,25) = HCF(95,70) = HCF(165,95) = HCF(260,165) = HCF(425,260) = HCF(685,425) .

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

Step 1: Since 94 > 5, we apply the division lemma to 94 and 5, to get

94 = 5 x 18 + 4

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get

5 = 4 x 1 + 1

Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 94 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(94,5) .

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

Step 1: Since 872 > 1, we apply the division lemma to 872 and 1, to get

872 = 1 x 872 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 872 is 1

Notice that 1 = HCF(872,1) .
