HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 748, 955, 715 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 748, 955, 715 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 748, 955, 715 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 748, 955, 715 is 1.

HCF(748, 955, 715) = 1

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

HCF of:

Highest common factor (HCF) of 748, 955, 715 is 1.

Highest Common Factor of 748,955,715 using Euclid's algorithm

Highest Common Factor of 748,955,715 is 1

Step 1: Since 955 > 748, we apply the division lemma to 955 and 748, to get

955 = 748 x 1 + 207

Step 2: Since the reminder 748 ≠ 0, we apply division lemma to 207 and 748, to get

748 = 207 x 3 + 127

Step 3: We consider the new divisor 207 and the new remainder 127, and apply the division lemma to get

207 = 127 x 1 + 80

We consider the new divisor 127 and the new remainder 80,and apply the division lemma to get

127 = 80 x 1 + 47

We consider the new divisor 80 and the new remainder 47,and apply the division lemma to get

80 = 47 x 1 + 33

We consider the new divisor 47 and the new remainder 33,and apply the division lemma to get

47 = 33 x 1 + 14

We consider the new divisor 33 and the new remainder 14,and apply the division lemma to get

33 = 14 x 2 + 5

We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get

14 = 5 x 2 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 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 748 and 955 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(33,14) = HCF(47,33) = HCF(80,47) = HCF(127,80) = HCF(207,127) = HCF(748,207) = HCF(955,748) .

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

Step 1: Since 715 > 1, we apply the division lemma to 715 and 1, to get

715 = 1 x 715 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 715 is 1

Notice that 1 = HCF(715,1) .
