HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 723, 913, 973 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 723, 913, 973 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 723, 913, 973 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 723, 913, 973 is 1.

HCF(723, 913, 973) = 1

Highest common factor (HCF) of 723, 913, 973 is 1.

Highest Common Factor of 723,913,973 using Euclid's algorithm

Highest Common Factor of 723,913,973 is 1

Step 1: Since 913 > 723, we apply the division lemma to 913 and 723, to get

913 = 723 x 1 + 190

Step 2: Since the reminder 723 ≠ 0, we apply division lemma to 190 and 723, to get

723 = 190 x 3 + 153

Step 3: We consider the new divisor 190 and the new remainder 153, and apply the division lemma to get

190 = 153 x 1 + 37

We consider the new divisor 153 and the new remainder 37,and apply the division lemma to get

153 = 37 x 4 + 5

We consider the new divisor 37 and the new remainder 5,and apply the division lemma to get

37 = 5 x 7 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 723 and 913 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(37,5) = HCF(153,37) = HCF(190,153) = HCF(723,190) = HCF(913,723) .

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

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

973 = 1 x 973 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 973 is 1

Notice that 1 = HCF(973,1) .
