HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 742, 429, 729 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 742, 429, 729 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 742, 429, 729 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 742, 429, 729 is 1.

HCF(742, 429, 729) = 1

Highest common factor (HCF) of 742, 429, 729 is 1.

Highest Common Factor of 742,429,729 using Euclid's algorithm

Highest Common Factor of 742,429,729 is 1

Step 1: Since 742 > 429, we apply the division lemma to 742 and 429, to get

742 = 429 x 1 + 313

Step 2: Since the reminder 429 ≠ 0, we apply division lemma to 313 and 429, to get

429 = 313 x 1 + 116

Step 3: We consider the new divisor 313 and the new remainder 116, and apply the division lemma to get

313 = 116 x 2 + 81

We consider the new divisor 116 and the new remainder 81,and apply the division lemma to get

116 = 81 x 1 + 35

We consider the new divisor 81 and the new remainder 35,and apply the division lemma to get

81 = 35 x 2 + 11

We consider the new divisor 35 and the new remainder 11,and apply the division lemma to get

35 = 11 x 3 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 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 742 and 429 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(35,11) = HCF(81,35) = HCF(116,81) = HCF(313,116) = HCF(429,313) = HCF(742,429) .

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

Step 1: Since 729 > 1, we apply the division lemma to 729 and 1, to get

729 = 1 x 729 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 729 is 1

Notice that 1 = HCF(729,1) .
