HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 481, 436, 120 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 481, 436, 120 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 481, 436, 120 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 481, 436, 120 is 1.

HCF(481, 436, 120) = 1

Highest common factor (HCF) of 481, 436, 120 is 1.

Highest Common Factor of 481,436,120 using Euclid's algorithm

Highest Common Factor of 481,436,120 is 1

Step 1: Since 481 > 436, we apply the division lemma to 481 and 436, to get

481 = 436 x 1 + 45

Step 2: Since the reminder 436 ≠ 0, we apply division lemma to 45 and 436, to get

436 = 45 x 9 + 31

Step 3: We consider the new divisor 45 and the new remainder 31, and apply the division lemma to get

45 = 31 x 1 + 14

We consider the new divisor 31 and the new remainder 14,and apply the division lemma to get

31 = 14 x 2 + 3

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

14 = 3 x 4 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 481 and 436 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(31,14) = HCF(45,31) = HCF(436,45) = HCF(481,436) .

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) .
