HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 940, 675, 768 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 940, 675, 768 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 940, 675, 768 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 940, 675, 768 is 1.

HCF(940, 675, 768) = 1

Highest common factor (HCF) of 940, 675, 768 is 1.

Highest Common Factor of 940,675,768 using Euclid's algorithm

Highest Common Factor of 940,675,768 is 1

Step 1: Since 940 > 675, we apply the division lemma to 940 and 675, to get

940 = 675 x 1 + 265

Step 2: Since the reminder 675 ≠ 0, we apply division lemma to 265 and 675, to get

675 = 265 x 2 + 145

Step 3: We consider the new divisor 265 and the new remainder 145, and apply the division lemma to get

265 = 145 x 1 + 120

We consider the new divisor 145 and the new remainder 120,and apply the division lemma to get

145 = 120 x 1 + 25

We consider the new divisor 120 and the new remainder 25,and apply the division lemma to get

120 = 25 x 4 + 20

We consider the new divisor 25 and the new remainder 20,and apply the division lemma to get

25 = 20 x 1 + 5

We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get

20 = 5 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 940 and 675 is 5

Notice that 5 = HCF(20,5) = HCF(25,20) = HCF(120,25) = HCF(145,120) = HCF(265,145) = HCF(675,265) = HCF(940,675) .

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

Step 1: Since 768 > 5, we apply the division lemma to 768 and 5, to get

768 = 5 x 153 + 3

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get

5 = 3 x 1 + 2

Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get

3 = 2 x 1 + 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 5 and 768 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(768,5) .
