HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 153, 571, 723 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 153, 571, 723 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 153, 571, 723 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 153, 571, 723 is 1.

HCF(153, 571, 723) = 1

Highest common factor (HCF) of 153, 571, 723 is 1.

Highest Common Factor of 153,571,723 using Euclid's algorithm

Highest Common Factor of 153,571,723 is 1

Step 1: Since 571 > 153, we apply the division lemma to 571 and 153, to get

571 = 153 x 3 + 112

Step 2: Since the reminder 153 ≠ 0, we apply division lemma to 112 and 153, to get

153 = 112 x 1 + 41

Step 3: We consider the new divisor 112 and the new remainder 41, and apply the division lemma to get

112 = 41 x 2 + 30

We consider the new divisor 41 and the new remainder 30,and apply the division lemma to get

41 = 30 x 1 + 11

We consider the new divisor 30 and the new remainder 11,and apply the division lemma to get

30 = 11 x 2 + 8

We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get

11 = 8 x 1 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 2

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 153 and 571 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(30,11) = HCF(41,30) = HCF(112,41) = HCF(153,112) = HCF(571,153) .


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

Step 1: Since 723 > 1, we apply the division lemma to 723 and 1, to get

723 = 1 x 723 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 723 is 1

Notice that 1 = HCF(723,1) .
