HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 751, 278, 840 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 751, 278, 840 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 751, 278, 840 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 751, 278, 840 is 1.

HCF(751, 278, 840) = 1

Highest common factor (HCF) of 751, 278, 840 is 1.

Highest Common Factor of 751,278,840 using Euclid's algorithm

Highest Common Factor of 751,278,840 is 1

Step 1: Since 751 > 278, we apply the division lemma to 751 and 278, to get

751 = 278 x 2 + 195

Step 2: Since the reminder 278 ≠ 0, we apply division lemma to 195 and 278, to get

278 = 195 x 1 + 83

Step 3: We consider the new divisor 195 and the new remainder 83, and apply the division lemma to get

195 = 83 x 2 + 29

We consider the new divisor 83 and the new remainder 29,and apply the division lemma to get

83 = 29 x 2 + 25

We consider the new divisor 29 and the new remainder 25,and apply the division lemma to get

29 = 25 x 1 + 4

We consider the new divisor 25 and the new remainder 4,and apply the division lemma to get

25 = 4 x 6 + 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 751 and 278 is 1

Notice that 1 = HCF(4,1) = HCF(25,4) = HCF(29,25) = HCF(83,29) = HCF(195,83) = HCF(278,195) = HCF(751,278) .

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

Step 1: Since 840 > 1, we apply the division lemma to 840 and 1, to get

840 = 1 x 840 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 840 is 1

Notice that 1 = HCF(840,1) .
