HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 845, 525, 245 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 845, 525, 245 is 5 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 845, 525, 245 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 845, 525, 245 is 5.

HCF(845, 525, 245) = 5

Highest common factor (HCF) of 845, 525, 245 is 5.

Highest Common Factor of 845,525,245 using Euclid's algorithm

Highest Common Factor of 845,525,245 is 5

Step 1: Since 845 > 525, we apply the division lemma to 845 and 525, to get

845 = 525 x 1 + 320

Step 2: Since the reminder 525 ≠ 0, we apply division lemma to 320 and 525, to get

525 = 320 x 1 + 205

Step 3: We consider the new divisor 320 and the new remainder 205, and apply the division lemma to get

320 = 205 x 1 + 115

We consider the new divisor 205 and the new remainder 115,and apply the division lemma to get

205 = 115 x 1 + 90

We consider the new divisor 115 and the new remainder 90,and apply the division lemma to get

115 = 90 x 1 + 25

We consider the new divisor 90 and the new remainder 25,and apply the division lemma to get

90 = 25 x 3 + 15

We consider the new divisor 25 and the new remainder 15,and apply the division lemma to get

25 = 15 x 1 + 10

We consider the new divisor 15 and the new remainder 10,and apply the division lemma to get

15 = 10 x 1 + 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 845 and 525 is 5

Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(25,15) = HCF(90,25) = HCF(115,90) = HCF(205,115) = HCF(320,205) = HCF(525,320) = HCF(845,525) .

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

Step 1: Since 245 > 5, we apply the division lemma to 245 and 5, to get

245 = 5 x 49 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 245 is 5

Notice that 5 = HCF(245,5) .
