HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 701, 973, 721 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 701, 973, 721 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 701, 973, 721 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 701, 973, 721 is 1.

HCF(701, 973, 721) = 1

Highest common factor (HCF) of 701, 973, 721 is 1.

Highest Common Factor of 701,973,721 using Euclid's algorithm

Highest Common Factor of 701,973,721 is 1

Step 1: Since 973 > 701, we apply the division lemma to 973 and 701, to get

973 = 701 x 1 + 272

Step 2: Since the reminder 701 ≠ 0, we apply division lemma to 272 and 701, to get

701 = 272 x 2 + 157

Step 3: We consider the new divisor 272 and the new remainder 157, and apply the division lemma to get

272 = 157 x 1 + 115

We consider the new divisor 157 and the new remainder 115,and apply the division lemma to get

157 = 115 x 1 + 42

We consider the new divisor 115 and the new remainder 42,and apply the division lemma to get

115 = 42 x 2 + 31

We consider the new divisor 42 and the new remainder 31,and apply the division lemma to get

42 = 31 x 1 + 11

We consider the new divisor 31 and the new remainder 11,and apply the division lemma to get

31 = 11 x 2 + 9

We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get

11 = 9 x 1 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 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 701 and 973 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(31,11) = HCF(42,31) = HCF(115,42) = HCF(157,115) = HCF(272,157) = HCF(701,272) = HCF(973,701) .

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

Step 1: Since 721 > 1, we apply the division lemma to 721 and 1, to get

721 = 1 x 721 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 721 is 1

Notice that 1 = HCF(721,1) .
