HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 281, 628, 946 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 281, 628, 946 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 281, 628, 946 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 281, 628, 946 is 1.

HCF(281, 628, 946) = 1

Highest common factor (HCF) of 281, 628, 946 is 1.

Highest Common Factor of 281,628,946 using Euclid's algorithm

Highest Common Factor of 281,628,946 is 1

Step 1: Since 628 > 281, we apply the division lemma to 628 and 281, to get

628 = 281 x 2 + 66

Step 2: Since the reminder 281 ≠ 0, we apply division lemma to 66 and 281, to get

281 = 66 x 4 + 17

Step 3: We consider the new divisor 66 and the new remainder 17, and apply the division lemma to get

66 = 17 x 3 + 15

We consider the new divisor 17 and the new remainder 15,and apply the division lemma to get

17 = 15 x 1 + 2

We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get

15 = 2 x 7 + 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 281 and 628 is 1

Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(17,15) = HCF(66,17) = HCF(281,66) = HCF(628,281) .

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

Step 1: Since 946 > 1, we apply the division lemma to 946 and 1, to get

946 = 1 x 946 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 946 is 1

Notice that 1 = HCF(946,1) .
