HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 145, 909, 553 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 145, 909, 553 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 145, 909, 553 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 145, 909, 553 is 1.

HCF(145, 909, 553) = 1

HCF of 145, 909, 553 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 145, 909, 553 is 1.

Highest Common Factor of 145,909,553 using Euclid's algorithm

Highest Common Factor of 145,909,553 is 1

Step 1: Since 909 > 145, we apply the division lemma to 909 and 145, to get

909 = 145 x 6 + 39

Step 2: Since the reminder 145 ≠ 0, we apply division lemma to 39 and 145, to get

145 = 39 x 3 + 28

Step 3: We consider the new divisor 39 and the new remainder 28, and apply the division lemma to get

39 = 28 x 1 + 11

We consider the new divisor 28 and the new remainder 11,and apply the division lemma to get

28 = 11 x 2 + 6

We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get

11 = 6 x 1 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma 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 145 and 909 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(28,11) = HCF(39,28) = HCF(145,39) = HCF(909,145) .

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

Step 1: Since 553 > 1, we apply the division lemma to 553 and 1, to get

553 = 1 x 553 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 553 is 1

Notice that 1 = HCF(553,1) .
