HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 632, 989, 145 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 632, 989, 145 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 632, 989, 145 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 632, 989, 145 is 1.

HCF(632, 989, 145) = 1

HCF of 632, 989, 145 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 632, 989, 145 is 1.

Highest Common Factor of 632,989,145 using Euclid's algorithm

Highest Common Factor of 632,989,145 is 1

Step 1: Since 989 > 632, we apply the division lemma to 989 and 632, to get

989 = 632 x 1 + 357

Step 2: Since the reminder 632 ≠ 0, we apply division lemma to 357 and 632, to get

632 = 357 x 1 + 275

Step 3: We consider the new divisor 357 and the new remainder 275, and apply the division lemma to get

357 = 275 x 1 + 82

We consider the new divisor 275 and the new remainder 82,and apply the division lemma to get

275 = 82 x 3 + 29

We consider the new divisor 82 and the new remainder 29,and apply the division lemma to get

82 = 29 x 2 + 24

We consider the new divisor 29 and the new remainder 24,and apply the division lemma to get

29 = 24 x 1 + 5

We consider the new divisor 24 and the new remainder 5,and apply the division lemma to get

24 = 5 x 4 + 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 632 and 989 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(24,5) = HCF(29,24) = HCF(82,29) = HCF(275,82) = HCF(357,275) = HCF(632,357) = HCF(989,632) .

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

Step 1: Since 145 > 1, we apply the division lemma to 145 and 1, to get

145 = 1 x 145 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 145 is 1

Notice that 1 = HCF(145,1) .
