HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 575, 1655, 5407 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 575, 1655, 5407 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 575, 1655, 5407 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 575, 1655, 5407 is 1.

HCF(575, 1655, 5407) = 1

Highest common factor (HCF) of 575, 1655, 5407 is 1.

Highest Common Factor of 575,1655,5407 using Euclid's algorithm

Highest Common Factor of 575,1655,5407 is 1

Step 1: Since 1655 > 575, we apply the division lemma to 1655 and 575, to get

1655 = 575 x 2 + 505

Step 2: Since the reminder 575 ≠ 0, we apply division lemma to 505 and 575, to get

575 = 505 x 1 + 70

Step 3: We consider the new divisor 505 and the new remainder 70, and apply the division lemma to get

505 = 70 x 7 + 15

We consider the new divisor 70 and the new remainder 15,and apply the division lemma to get

70 = 15 x 4 + 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 575 and 1655 is 5

Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(70,15) = HCF(505,70) = HCF(575,505) = HCF(1655,575) .

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

Step 1: Since 5407 > 5, we apply the division lemma to 5407 and 5, to get

5407 = 5 x 1081 + 2

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

5 = 2 x 2 + 1

Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 5407 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(5407,5) .
