HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 942, 574, 251 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 942, 574, 251 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 942, 574, 251 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 942, 574, 251 is 1.

HCF(942, 574, 251) = 1

Highest common factor (HCF) of 942, 574, 251 is 1.

Highest Common Factor of 942,574,251 using Euclid's algorithm

Highest Common Factor of 942,574,251 is 1

Step 1: Since 942 > 574, we apply the division lemma to 942 and 574, to get

942 = 574 x 1 + 368

Step 2: Since the reminder 574 ≠ 0, we apply division lemma to 368 and 574, to get

574 = 368 x 1 + 206

Step 3: We consider the new divisor 368 and the new remainder 206, and apply the division lemma to get

368 = 206 x 1 + 162

We consider the new divisor 206 and the new remainder 162,and apply the division lemma to get

206 = 162 x 1 + 44

We consider the new divisor 162 and the new remainder 44,and apply the division lemma to get

162 = 44 x 3 + 30

We consider the new divisor 44 and the new remainder 30,and apply the division lemma to get

44 = 30 x 1 + 14

We consider the new divisor 30 and the new remainder 14,and apply the division lemma to get

30 = 14 x 2 + 2

We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get

14 = 2 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 942 and 574 is 2

Notice that 2 = HCF(14,2) = HCF(30,14) = HCF(44,30) = HCF(162,44) = HCF(206,162) = HCF(368,206) = HCF(574,368) = HCF(942,574) .

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

Step 1: Since 251 > 2, we apply the division lemma to 251 and 2, to get

251 = 2 x 125 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 251 is 1

Notice that 1 = HCF(2,1) = HCF(251,2) .
