HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 125, 721, 208 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 125, 721, 208 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 125, 721, 208 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 125, 721, 208 is 1.

HCF(125, 721, 208) = 1

Highest common factor (HCF) of 125, 721, 208 is 1.

Highest Common Factor of 125,721,208 using Euclid's algorithm

Highest Common Factor of 125,721,208 is 1

Step 1: Since 721 > 125, we apply the division lemma to 721 and 125, to get

721 = 125 x 5 + 96

Step 2: Since the reminder 125 ≠ 0, we apply division lemma to 96 and 125, to get

125 = 96 x 1 + 29

Step 3: We consider the new divisor 96 and the new remainder 29, and apply the division lemma to get

96 = 29 x 3 + 9

We consider the new divisor 29 and the new remainder 9,and apply the division lemma to get

29 = 9 x 3 + 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 125 and 721 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(29,9) = HCF(96,29) = HCF(125,96) = HCF(721,125) .

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

Step 1: Since 208 > 1, we apply the division lemma to 208 and 1, to get

208 = 1 x 208 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 208 is 1

Notice that 1 = HCF(208,1) .
