HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 785, 548, 698, 395 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 785, 548, 698, 395 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 785, 548, 698, 395 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 785, 548, 698, 395 is 1.

HCF(785, 548, 698, 395) = 1

Highest common factor (HCF) of 785, 548, 698, 395 is 1.

Highest Common Factor of 785,548,698,395 using Euclid's algorithm

Highest Common Factor of 785,548,698,395 is 1

Step 1: Since 785 > 548, we apply the division lemma to 785 and 548, to get

785 = 548 x 1 + 237

Step 2: Since the reminder 548 ≠ 0, we apply division lemma to 237 and 548, to get

548 = 237 x 2 + 74

Step 3: We consider the new divisor 237 and the new remainder 74, and apply the division lemma to get

237 = 74 x 3 + 15

We consider the new divisor 74 and the new remainder 15,and apply the division lemma to get

74 = 15 x 4 + 14

We consider the new divisor 15 and the new remainder 14,and apply the division lemma to get

15 = 14 x 1 + 1

We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get

14 = 1 x 14 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 785 and 548 is 1

Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(74,15) = HCF(237,74) = HCF(548,237) = HCF(785,548) .

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

Step 1: Since 698 > 1, we apply the division lemma to 698 and 1, to get

698 = 1 x 698 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 698 is 1

Notice that 1 = HCF(698,1) .

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

Step 1: Since 395 > 1, we apply the division lemma to 395 and 1, to get

395 = 1 x 395 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 395 is 1

Notice that 1 = HCF(395,1) .
