HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 831, 578, 362, 38 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 831, 578, 362, 38 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 831, 578, 362, 38 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 831, 578, 362, 38 is 1.

HCF(831, 578, 362, 38) = 1

Highest common factor (HCF) of 831, 578, 362, 38 is 1.

Highest Common Factor of 831,578,362,38 using Euclid's algorithm

Highest Common Factor of 831,578,362,38 is 1

Step 1: Since 831 > 578, we apply the division lemma to 831 and 578, to get

831 = 578 x 1 + 253

Step 2: Since the reminder 578 ≠ 0, we apply division lemma to 253 and 578, to get

578 = 253 x 2 + 72

Step 3: We consider the new divisor 253 and the new remainder 72, and apply the division lemma to get

253 = 72 x 3 + 37

We consider the new divisor 72 and the new remainder 37,and apply the division lemma to get

72 = 37 x 1 + 35

We consider the new divisor 37 and the new remainder 35,and apply the division lemma to get

37 = 35 x 1 + 2

We consider the new divisor 35 and the new remainder 2,and apply the division lemma to get

35 = 2 x 17 + 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 831 and 578 is 1

Notice that 1 = HCF(2,1) = HCF(35,2) = HCF(37,35) = HCF(72,37) = HCF(253,72) = HCF(578,253) = HCF(831,578) .

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

Step 1: Since 362 > 1, we apply the division lemma to 362 and 1, to get

362 = 1 x 362 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 362 is 1

Notice that 1 = HCF(362,1) .

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

Step 1: Since 38 > 1, we apply the division lemma to 38 and 1, to get

38 = 1 x 38 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 38 is 1

Notice that 1 = HCF(38,1) .
