HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 965, 370, 768, 655 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 965, 370, 768, 655 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 965, 370, 768, 655 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 965, 370, 768, 655 is 1.

HCF(965, 370, 768, 655) = 1

Highest common factor (HCF) of 965, 370, 768, 655 is 1.

Highest Common Factor of 965,370,768,655 using Euclid's algorithm

Highest Common Factor of 965,370,768,655 is 1

Step 1: Since 965 > 370, we apply the division lemma to 965 and 370, to get

965 = 370 x 2 + 225

Step 2: Since the reminder 370 ≠ 0, we apply division lemma to 225 and 370, to get

370 = 225 x 1 + 145

Step 3: We consider the new divisor 225 and the new remainder 145, and apply the division lemma to get

225 = 145 x 1 + 80

We consider the new divisor 145 and the new remainder 80,and apply the division lemma to get

145 = 80 x 1 + 65

We consider the new divisor 80 and the new remainder 65,and apply the division lemma to get

80 = 65 x 1 + 15

We consider the new divisor 65 and the new remainder 15,and apply the division lemma to get

65 = 15 x 4 + 5

We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get

15 = 5 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 965 and 370 is 5

Notice that 5 = HCF(15,5) = HCF(65,15) = HCF(80,65) = HCF(145,80) = HCF(225,145) = HCF(370,225) = HCF(965,370) .

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) .

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

Step 1: Since 655 > 1, we apply the division lemma to 655 and 1, to get

655 = 1 x 655 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 655 is 1

Notice that 1 = HCF(655,1) .
