HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1405, 2698 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 1405, 2698 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 1405, 2698 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 1405, 2698 is 1.

HCF(1405, 2698) = 1

Highest Common Factor of 1405,2698 using Euclid's algorithm

Highest Common Factor of 1405,2698 is 1

Step 1: Since 2698 > 1405, we apply the division lemma to 2698 and 1405, to get

2698 = 1405 x 1 + 1293

Step 2: Since the reminder 1405 ≠ 0, we apply division lemma to 1293 and 1405, to get

1405 = 1293 x 1 + 112

Step 3: We consider the new divisor 1293 and the new remainder 112, and apply the division lemma to get

1293 = 112 x 11 + 61

We consider the new divisor 112 and the new remainder 61,and apply the division lemma to get

112 = 61 x 1 + 51

We consider the new divisor 61 and the new remainder 51,and apply the division lemma to get

61 = 51 x 1 + 10

We consider the new divisor 51 and the new remainder 10,and apply the division lemma to get

51 = 10 x 5 + 1

We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1405 and 2698 is 1

Notice that 1 = HCF(10,1) = HCF(51,10) = HCF(61,51) = HCF(112,61) = HCF(1293,112) = HCF(1405,1293) = HCF(2698,1405) .
