HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 768, 99617 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 768, 99617 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 768, 99617 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 768, 99617 is 1.

HCF(768, 99617) = 1

Highest common factor (HCF) of 768, 99617 is 1.

Highest Common Factor of 768,99617 using Euclid's algorithm

Highest Common Factor of 768,99617 is 1

Step 1: Since 99617 > 768, we apply the division lemma to 99617 and 768, to get

99617 = 768 x 129 + 545

Step 2: Since the reminder 768 ≠ 0, we apply division lemma to 545 and 768, to get

768 = 545 x 1 + 223

Step 3: We consider the new divisor 545 and the new remainder 223, and apply the division lemma to get

545 = 223 x 2 + 99

We consider the new divisor 223 and the new remainder 99,and apply the division lemma to get

223 = 99 x 2 + 25

We consider the new divisor 99 and the new remainder 25,and apply the division lemma to get

99 = 25 x 3 + 24

We consider the new divisor 25 and the new remainder 24,and apply the division lemma to get

25 = 24 x 1 + 1

We consider the new divisor 24 and the new remainder 1,and apply the division lemma to get

24 = 1 x 24 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 768 and 99617 is 1

Notice that 1 = HCF(24,1) = HCF(25,24) = HCF(99,25) = HCF(223,99) = HCF(545,223) = HCF(768,545) = HCF(99617,768) .
