HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 480, 169, 75 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 480, 169, 75 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 480, 169, 75 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 480, 169, 75 is 1.

HCF(480, 169, 75) = 1

Highest Common Factor of 480,169,75 using Euclid's algorithm

Highest Common Factor of 480,169,75 is 1

Step 1: Since 480 > 169, we apply the division lemma to 480 and 169, to get

480 = 169 x 2 + 142

Step 2: Since the reminder 169 ≠ 0, we apply division lemma to 142 and 169, to get

169 = 142 x 1 + 27

Step 3: We consider the new divisor 142 and the new remainder 27, and apply the division lemma to get

142 = 27 x 5 + 7

We consider the new divisor 27 and the new remainder 7,and apply the division lemma to get

27 = 7 x 3 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 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 480 and 169 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(27,7) = HCF(142,27) = HCF(169,142) = HCF(480,169) .

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

Step 1: Since 75 > 1, we apply the division lemma to 75 and 1, to get

75 = 1 x 75 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 75 is 1

Notice that 1 = HCF(75,1) .
