HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 358, 435, 769 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 358, 435, 769 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 358, 435, 769 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 358, 435, 769 is 1.

HCF(358, 435, 769) = 1

Highest common factor (HCF) of 358, 435, 769 is 1.

Highest Common Factor of 358,435,769 using Euclid's algorithm

Highest Common Factor of 358,435,769 is 1

Step 1: Since 435 > 358, we apply the division lemma to 435 and 358, to get

435 = 358 x 1 + 77

Step 2: Since the reminder 358 ≠ 0, we apply division lemma to 77 and 358, to get

358 = 77 x 4 + 50

Step 3: We consider the new divisor 77 and the new remainder 50, and apply the division lemma to get

77 = 50 x 1 + 27

We consider the new divisor 50 and the new remainder 27,and apply the division lemma to get

50 = 27 x 1 + 23

We consider the new divisor 27 and the new remainder 23,and apply the division lemma to get

27 = 23 x 1 + 4

We consider the new divisor 23 and the new remainder 4,and apply the division lemma to get

23 = 4 x 5 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 358 and 435 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(23,4) = HCF(27,23) = HCF(50,27) = HCF(77,50) = HCF(358,77) = HCF(435,358) .

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

Step 1: Since 769 > 1, we apply the division lemma to 769 and 1, to get

769 = 1 x 769 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 769 is 1

Notice that 1 = HCF(769,1) .
