HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 481, 785, 147 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 481, 785, 147 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 481, 785, 147 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 481, 785, 147 is 1.

HCF(481, 785, 147) = 1

Highest common factor (HCF) of 481, 785, 147 is 1.

Highest Common Factor of 481,785,147 using Euclid's algorithm

Highest Common Factor of 481,785,147 is 1

Step 1: Since 785 > 481, we apply the division lemma to 785 and 481, to get

785 = 481 x 1 + 304

Step 2: Since the reminder 481 ≠ 0, we apply division lemma to 304 and 481, to get

481 = 304 x 1 + 177

Step 3: We consider the new divisor 304 and the new remainder 177, and apply the division lemma to get

304 = 177 x 1 + 127

We consider the new divisor 177 and the new remainder 127,and apply the division lemma to get

177 = 127 x 1 + 50

We consider the new divisor 127 and the new remainder 50,and apply the division lemma to get

127 = 50 x 2 + 27

We consider the new divisor 50 and the new remainder 27,and apply the division lemma to get

50 = 27 x 1 + 23

We consider the new divisor 27 and the new remainder 23,and apply the division lemma to get

27 = 23 x 1 + 4

We consider the new divisor 23 and the new remainder 4,and apply the division lemma to get

23 = 4 x 5 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

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

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 481 and 785 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(23,4) = HCF(27,23) = HCF(50,27) = HCF(127,50) = HCF(177,127) = HCF(304,177) = HCF(481,304) = HCF(785,481) .

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

Step 1: Since 147 > 1, we apply the division lemma to 147 and 1, to get

147 = 1 x 147 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 147 is 1

Notice that 1 = HCF(147,1) .
