HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 700, 145, 202 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 700, 145, 202 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 700, 145, 202 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 700, 145, 202 is 1.

HCF(700, 145, 202) = 1

HCF of 700, 145, 202 using Euclid's algorithm

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

Highest common factor (HCF) of 700, 145, 202 is 1.

Highest Common Factor of 700,145,202 using Euclid's algorithm

Highest Common Factor of 700,145,202 is 1

Step 1: Since 700 > 145, we apply the division lemma to 700 and 145, to get

700 = 145 x 4 + 120

Step 2: Since the reminder 145 ≠ 0, we apply division lemma to 120 and 145, to get

145 = 120 x 1 + 25

Step 3: We consider the new divisor 120 and the new remainder 25, and apply the division lemma to get

120 = 25 x 4 + 20

We consider the new divisor 25 and the new remainder 20,and apply the division lemma to get

25 = 20 x 1 + 5

We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get

20 = 5 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 700 and 145 is 5

Notice that 5 = HCF(20,5) = HCF(25,20) = HCF(120,25) = HCF(145,120) = HCF(700,145) .

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

Step 1: Since 202 > 5, we apply the division lemma to 202 and 5, to get

202 = 5 x 40 + 2

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get

5 = 2 x 2 + 1

Step 3: 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 5 and 202 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(202,5) .
