HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1234, 7449 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 1234, 7449 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 1234, 7449 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 1234, 7449 is 1.

HCF(1234, 7449) = 1

Highest Common Factor of 1234,7449 using Euclid's algorithm

Highest Common Factor of 1234,7449 is 1

Step 1: Since 7449 > 1234, we apply the division lemma to 7449 and 1234, to get

7449 = 1234 x 6 + 45

Step 2: Since the reminder 1234 ≠ 0, we apply division lemma to 45 and 1234, to get

1234 = 45 x 27 + 19

Step 3: We consider the new divisor 45 and the new remainder 19, and apply the division lemma to get

45 = 19 x 2 + 7

We consider the new divisor 19 and the new remainder 7,and apply the division lemma to get

19 = 7 x 2 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 1234 and 7449 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(19,7) = HCF(45,19) = HCF(1234,45) = HCF(7449,1234) .
