HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 142, 529, 803, 97 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 142, 529, 803, 97 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 142, 529, 803, 97 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 142, 529, 803, 97 is 1.

HCF(142, 529, 803, 97) = 1

Highest Common Factor of 142,529,803,97 using Euclid's algorithm

Highest Common Factor of 142,529,803,97 is 1

Step 1: Since 529 > 142, we apply the division lemma to 529 and 142, to get

529 = 142 x 3 + 103

Step 2: Since the reminder 142 ≠ 0, we apply division lemma to 103 and 142, to get

142 = 103 x 1 + 39

Step 3: We consider the new divisor 103 and the new remainder 39, and apply the division lemma to get

103 = 39 x 2 + 25

We consider the new divisor 39 and the new remainder 25,and apply the division lemma to get

39 = 25 x 1 + 14

We consider the new divisor 25 and the new remainder 14,and apply the division lemma to get

25 = 14 x 1 + 11

We consider the new divisor 14 and the new remainder 11,and apply the division lemma to get

14 = 11 x 1 + 3

We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get

11 = 3 x 3 + 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 142 and 529 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(25,14) = HCF(39,25) = HCF(103,39) = HCF(142,103) = HCF(529,142) .

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

Step 1: Since 803 > 1, we apply the division lemma to 803 and 1, to get

803 = 1 x 803 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 803 is 1

Notice that 1 = HCF(803,1) .

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

Step 1: Since 97 > 1, we apply the division lemma to 97 and 1, to get

97 = 1 x 97 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 97 is 1

Notice that 1 = HCF(97,1) .
