HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 545, 494, 942 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 545, 494, 942 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 545, 494, 942 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 545, 494, 942 is 1.

HCF(545, 494, 942) = 1

Highest common factor (HCF) of 545, 494, 942 is 1.

Highest Common Factor of 545,494,942 using Euclid's algorithm

Highest Common Factor of 545,494,942 is 1

Step 1: Since 545 > 494, we apply the division lemma to 545 and 494, to get

545 = 494 x 1 + 51

Step 2: Since the reminder 494 ≠ 0, we apply division lemma to 51 and 494, to get

494 = 51 x 9 + 35

Step 3: We consider the new divisor 51 and the new remainder 35, and apply the division lemma to get

51 = 35 x 1 + 16

We consider the new divisor 35 and the new remainder 16,and apply the division lemma to get

35 = 16 x 2 + 3

We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get

16 = 3 x 5 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 545 and 494 is 1

Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(35,16) = HCF(51,35) = HCF(494,51) = HCF(545,494) .

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

Step 1: Since 942 > 1, we apply the division lemma to 942 and 1, to get

942 = 1 x 942 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 942 is 1

Notice that 1 = HCF(942,1) .
