HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 820, 581, 98, 790 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 820, 581, 98, 790 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 820, 581, 98, 790 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 820, 581, 98, 790 is 1.

HCF(820, 581, 98, 790) = 1

Highest Common Factor of 820,581,98,790 using Euclid's algorithm

Highest Common Factor of 820,581,98,790 is 1

Step 1: Since 820 > 581, we apply the division lemma to 820 and 581, to get

820 = 581 x 1 + 239

Step 2: Since the reminder 581 ≠ 0, we apply division lemma to 239 and 581, to get

581 = 239 x 2 + 103

Step 3: We consider the new divisor 239 and the new remainder 103, and apply the division lemma to get

239 = 103 x 2 + 33

We consider the new divisor 103 and the new remainder 33,and apply the division lemma to get

103 = 33 x 3 + 4

We consider the new divisor 33 and the new remainder 4,and apply the division lemma to get

33 = 4 x 8 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 820 and 581 is 1

Notice that 1 = HCF(4,1) = HCF(33,4) = HCF(103,33) = HCF(239,103) = HCF(581,239) = HCF(820,581) .


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

Step 1: Since 98 > 1, we apply the division lemma to 98 and 1, to get

98 = 1 x 98 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 98 is 1

Notice that 1 = HCF(98,1) .


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

Step 1: Since 790 > 1, we apply the division lemma to 790 and 1, to get

790 = 1 x 790 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 790 is 1

Notice that 1 = HCF(790,1) .
