HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 872, 743, 602 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 872, 743, 602 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 872, 743, 602 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 872, 743, 602 is 1.

HCF(872, 743, 602) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 872, 743, 602 is 1.

Highest Common Factor of 872,743,602 using Euclid's algorithm

Highest Common Factor of 872,743,602 is 1

Step 1: Since 872 > 743, we apply the division lemma to 872 and 743, to get

872 = 743 x 1 + 129

Step 2: Since the reminder 743 ≠ 0, we apply division lemma to 129 and 743, to get

743 = 129 x 5 + 98

Step 3: We consider the new divisor 129 and the new remainder 98, and apply the division lemma to get

129 = 98 x 1 + 31

We consider the new divisor 98 and the new remainder 31,and apply the division lemma to get

98 = 31 x 3 + 5

We consider the new divisor 31 and the new remainder 5,and apply the division lemma to get

31 = 5 x 6 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 872 and 743 is 1

Notice that 1 = HCF(5,1) = HCF(31,5) = HCF(98,31) = HCF(129,98) = HCF(743,129) = HCF(872,743) .

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

Step 1: Since 602 > 1, we apply the division lemma to 602 and 1, to get

602 = 1 x 602 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 602 is 1

Notice that 1 = HCF(602,1) .
