HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 927, 840, 454 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 927, 840, 454 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 927, 840, 454 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 927, 840, 454 is 1.

HCF(927, 840, 454) = 1

Highest common factor (HCF) of 927, 840, 454 is 1.

Highest Common Factor of 927,840,454 using Euclid's algorithm

Highest Common Factor of 927,840,454 is 1

Step 1: Since 927 > 840, we apply the division lemma to 927 and 840, to get

927 = 840 x 1 + 87

Step 2: Since the reminder 840 ≠ 0, we apply division lemma to 87 and 840, to get

840 = 87 x 9 + 57

Step 3: We consider the new divisor 87 and the new remainder 57, and apply the division lemma to get

87 = 57 x 1 + 30

We consider the new divisor 57 and the new remainder 30,and apply the division lemma to get

57 = 30 x 1 + 27

We consider the new divisor 30 and the new remainder 27,and apply the division lemma to get

30 = 27 x 1 + 3

We consider the new divisor 27 and the new remainder 3,and apply the division lemma to get

27 = 3 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 927 and 840 is 3

Notice that 3 = HCF(27,3) = HCF(30,27) = HCF(57,30) = HCF(87,57) = HCF(840,87) = HCF(927,840) .

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

Step 1: Since 454 > 3, we apply the division lemma to 454 and 3, to get

454 = 3 x 151 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 454 is 1

Notice that 1 = HCF(3,1) = HCF(454,3) .
