HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 351, 975, 45 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 351, 975, 45 is 3 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 351, 975, 45 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 351, 975, 45 is 3.

HCF(351, 975, 45) = 3

HCF of 351, 975, 45 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 351, 975, 45 is 3.

Highest Common Factor of 351,975,45 using Euclid's algorithm

Highest Common Factor of 351,975,45 is 3

Step 1: Since 975 > 351, we apply the division lemma to 975 and 351, to get

975 = 351 x 2 + 273

Step 2: Since the reminder 351 ≠ 0, we apply division lemma to 273 and 351, to get

351 = 273 x 1 + 78

Step 3: We consider the new divisor 273 and the new remainder 78, and apply the division lemma to get

273 = 78 x 3 + 39

We consider the new divisor 78 and the new remainder 39, and apply the division lemma to get

78 = 39 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 39, the HCF of 351 and 975 is 39

Notice that 39 = HCF(78,39) = HCF(273,78) = HCF(351,273) = HCF(975,351) .


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

Step 1: Since 45 > 39, we apply the division lemma to 45 and 39, to get

45 = 39 x 1 + 6

Step 2: Since the reminder 39 ≠ 0, we apply division lemma to 6 and 39, to get

39 = 6 x 6 + 3

Step 3: We consider the new divisor 6 and the new remainder 3, and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 39 and 45 is 3

Notice that 3 = HCF(6,3) = HCF(39,6) = HCF(45,39) .
