HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 915, 574, 120, 790 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 915, 574, 120, 790 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 915, 574, 120, 790 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 915, 574, 120, 790 is 1.

HCF(915, 574, 120, 790) = 1

Highest common factor (HCF) of 915, 574, 120, 790 is 1.

Highest Common Factor of 915,574,120,790 using Euclid's algorithm

Highest Common Factor of 915,574,120,790 is 1

Step 1: Since 915 > 574, we apply the division lemma to 915 and 574, to get

915 = 574 x 1 + 341

Step 2: Since the reminder 574 ≠ 0, we apply division lemma to 341 and 574, to get

574 = 341 x 1 + 233

Step 3: We consider the new divisor 341 and the new remainder 233, and apply the division lemma to get

341 = 233 x 1 + 108

We consider the new divisor 233 and the new remainder 108,and apply the division lemma to get

233 = 108 x 2 + 17

We consider the new divisor 108 and the new remainder 17,and apply the division lemma to get

108 = 17 x 6 + 6

We consider the new divisor 17 and the new remainder 6,and apply the division lemma to get

17 = 6 x 2 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 915 and 574 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(17,6) = HCF(108,17) = HCF(233,108) = HCF(341,233) = HCF(574,341) = HCF(915,574) .


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

Step 1: Since 120 > 1, we apply the division lemma to 120 and 1, to get

120 = 1 x 120 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 120 is 1

Notice that 1 = HCF(120,1) .


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

Step 1: Since 790 > 1, we apply the division lemma to 790 and 1, to get

790 = 1 x 790 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 790 is 1

Notice that 1 = HCF(790,1) .
