HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 781, 574, 141 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 781, 574, 141 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 781, 574, 141 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 781, 574, 141 is 1.

HCF(781, 574, 141) = 1

Highest common factor (HCF) of 781, 574, 141 is 1.

Highest Common Factor of 781,574,141 using Euclid's algorithm

Highest Common Factor of 781,574,141 is 1

Step 1: Since 781 > 574, we apply the division lemma to 781 and 574, to get

781 = 574 x 1 + 207

Step 2: Since the reminder 574 ≠ 0, we apply division lemma to 207 and 574, to get

574 = 207 x 2 + 160

Step 3: We consider the new divisor 207 and the new remainder 160, and apply the division lemma to get

207 = 160 x 1 + 47

We consider the new divisor 160 and the new remainder 47,and apply the division lemma to get

160 = 47 x 3 + 19

We consider the new divisor 47 and the new remainder 19,and apply the division lemma to get

47 = 19 x 2 + 9

We consider the new divisor 19 and the new remainder 9,and apply the division lemma to get

19 = 9 x 2 + 1

We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 781 and 574 is 1

Notice that 1 = HCF(9,1) = HCF(19,9) = HCF(47,19) = HCF(160,47) = HCF(207,160) = HCF(574,207) = HCF(781,574) .

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

Step 1: Since 141 > 1, we apply the division lemma to 141 and 1, to get

141 = 1 x 141 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 141 is 1

Notice that 1 = HCF(141,1) .
