HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 175, 655, 158, 618 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 175, 655, 158, 618 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 175, 655, 158, 618 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 175, 655, 158, 618 is 1.

HCF(175, 655, 158, 618) = 1

Highest common factor (HCF) of 175, 655, 158, 618 is 1.

Highest Common Factor of 175,655,158,618 using Euclid's algorithm

Highest Common Factor of 175,655,158,618 is 1

Step 1: Since 655 > 175, we apply the division lemma to 655 and 175, to get

655 = 175 x 3 + 130

Step 2: Since the reminder 175 ≠ 0, we apply division lemma to 130 and 175, to get

175 = 130 x 1 + 45

Step 3: We consider the new divisor 130 and the new remainder 45, and apply the division lemma to get

130 = 45 x 2 + 40

We consider the new divisor 45 and the new remainder 40,and apply the division lemma to get

45 = 40 x 1 + 5

We consider the new divisor 40 and the new remainder 5,and apply the division lemma to get

40 = 5 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 175 and 655 is 5

Notice that 5 = HCF(40,5) = HCF(45,40) = HCF(130,45) = HCF(175,130) = HCF(655,175) .

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

Step 1: Since 158 > 5, we apply the division lemma to 158 and 5, to get

158 = 5 x 31 + 3

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get

5 = 3 x 1 + 2

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

3 = 2 x 1 + 1

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 158 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(158,5) .

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

Step 1: Since 618 > 1, we apply the division lemma to 618 and 1, to get

618 = 1 x 618 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 618 is 1

Notice that 1 = HCF(618,1) .
