HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 615, 763 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 870, 615, 763 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 870, 615, 763 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 870, 615, 763 is 1.

HCF(870, 615, 763) = 1

HCF of 870, 615, 763 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 870, 615, 763 is 1.

Highest Common Factor of 870,615,763 using Euclid's algorithm

Highest Common Factor of 870,615,763 is 1

Step 1: Since 870 > 615, we apply the division lemma to 870 and 615, to get

870 = 615 x 1 + 255

Step 2: Since the reminder 615 ≠ 0, we apply division lemma to 255 and 615, to get

615 = 255 x 2 + 105

Step 3: We consider the new divisor 255 and the new remainder 105, and apply the division lemma to get

255 = 105 x 2 + 45

We consider the new divisor 105 and the new remainder 45,and apply the division lemma to get

105 = 45 x 2 + 15

We consider the new divisor 45 and the new remainder 15,and apply the division lemma to get

45 = 15 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 870 and 615 is 15

Notice that 15 = HCF(45,15) = HCF(105,45) = HCF(255,105) = HCF(615,255) = HCF(870,615) .

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

Step 1: Since 763 > 15, we apply the division lemma to 763 and 15, to get

763 = 15 x 50 + 13

Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 13 and 15, to get

15 = 13 x 1 + 2

Step 3: We consider the new divisor 13 and the new remainder 2, and apply the division lemma to get

13 = 2 x 6 + 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 15 and 763 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(763,15) .
