HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 30, 75, 74, 375 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 30, 75, 74, 375 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 30, 75, 74, 375 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 30, 75, 74, 375 is 1.

HCF(30, 75, 74, 375) = 1

HCF of 30, 75, 74, 375 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 30, 75, 74, 375 is 1.

Highest Common Factor of 30,75,74,375 using Euclid's algorithm

Highest Common Factor of 30,75,74,375 is 1

Step 1: Since 75 > 30, we apply the division lemma to 75 and 30, to get

75 = 30 x 2 + 15

Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 15 and 30, to get

30 = 15 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 30 and 75 is 15

Notice that 15 = HCF(30,15) = HCF(75,30) .


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

Step 1: Since 74 > 15, we apply the division lemma to 74 and 15, to get

74 = 15 x 4 + 14

Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 14 and 15, to get

15 = 14 x 1 + 1

Step 3: We consider the new divisor 14 and the new remainder 1, and apply the division lemma to get

14 = 1 x 14 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 15 and 74 is 1

Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(74,15) .


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

Step 1: Since 375 > 1, we apply the division lemma to 375 and 1, to get

375 = 1 x 375 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 375 is 1

Notice that 1 = HCF(375,1) .
