HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 755, 357, 407 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 755, 357, 407 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 755, 357, 407 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 755, 357, 407 is 1.

HCF(755, 357, 407) = 1

Highest common factor (HCF) of 755, 357, 407 is 1.

Highest Common Factor of 755,357,407 using Euclid's algorithm

Highest Common Factor of 755,357,407 is 1

Step 1: Since 755 > 357, we apply the division lemma to 755 and 357, to get

755 = 357 x 2 + 41

Step 2: Since the reminder 357 ≠ 0, we apply division lemma to 41 and 357, to get

357 = 41 x 8 + 29

Step 3: We consider the new divisor 41 and the new remainder 29, and apply the division lemma to get

41 = 29 x 1 + 12

We consider the new divisor 29 and the new remainder 12,and apply the division lemma to get

29 = 12 x 2 + 5

We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get

12 = 5 x 2 + 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 755 and 357 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(29,12) = HCF(41,29) = HCF(357,41) = HCF(755,357) .

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

Step 1: Since 407 > 1, we apply the division lemma to 407 and 1, to get

407 = 1 x 407 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 407 is 1

Notice that 1 = HCF(407,1) .
