HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 783, 440, 838 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 783, 440, 838 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 783, 440, 838 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 783, 440, 838 is 1.

HCF(783, 440, 838) = 1

Highest common factor (HCF) of 783, 440, 838 is 1.

Highest Common Factor of 783,440,838 using Euclid's algorithm

Highest Common Factor of 783,440,838 is 1

Step 1: Since 783 > 440, we apply the division lemma to 783 and 440, to get

783 = 440 x 1 + 343

Step 2: Since the reminder 440 ≠ 0, we apply division lemma to 343 and 440, to get

440 = 343 x 1 + 97

Step 3: We consider the new divisor 343 and the new remainder 97, and apply the division lemma to get

343 = 97 x 3 + 52

We consider the new divisor 97 and the new remainder 52,and apply the division lemma to get

97 = 52 x 1 + 45

We consider the new divisor 52 and the new remainder 45,and apply the division lemma to get

52 = 45 x 1 + 7

We consider the new divisor 45 and the new remainder 7,and apply the division lemma to get

45 = 7 x 6 + 3

We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get

7 = 3 x 2 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 783 and 440 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(45,7) = HCF(52,45) = HCF(97,52) = HCF(343,97) = HCF(440,343) = HCF(783,440) .

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

Step 1: Since 838 > 1, we apply the division lemma to 838 and 1, to get

838 = 1 x 838 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 838 is 1

Notice that 1 = HCF(838,1) .
