HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 924, 281, 55, 745 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 924, 281, 55, 745 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 924, 281, 55, 745 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 924, 281, 55, 745 is 1.

HCF(924, 281, 55, 745) = 1

Highest Common Factor of 924,281,55,745 using Euclid's algorithm

Highest Common Factor of 924,281,55,745 is 1

Step 1: Since 924 > 281, we apply the division lemma to 924 and 281, to get

924 = 281 x 3 + 81

Step 2: Since the reminder 281 ≠ 0, we apply division lemma to 81 and 281, to get

281 = 81 x 3 + 38

Step 3: We consider the new divisor 81 and the new remainder 38, and apply the division lemma to get

81 = 38 x 2 + 5

We consider the new divisor 38 and the new remainder 5,and apply the division lemma to get

38 = 5 x 7 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 924 and 281 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(38,5) = HCF(81,38) = HCF(281,81) = HCF(924,281) .

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

Step 1: Since 55 > 1, we apply the division lemma to 55 and 1, to get

55 = 1 x 55 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 55 is 1

Notice that 1 = HCF(55,1) .

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

Step 1: Since 745 > 1, we apply the division lemma to 745 and 1, to get

745 = 1 x 745 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 745 is 1

Notice that 1 = HCF(745,1) .
