HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 789, 435, 379 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 789, 435, 379 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 789, 435, 379 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 789, 435, 379 is 1.

HCF(789, 435, 379) = 1

Highest Common Factor of 789,435,379 using Euclid's algorithm

Highest Common Factor of 789,435,379 is 1

Step 1: Since 789 > 435, we apply the division lemma to 789 and 435, to get

789 = 435 x 1 + 354

Step 2: Since the reminder 435 ≠ 0, we apply division lemma to 354 and 435, to get

435 = 354 x 1 + 81

Step 3: We consider the new divisor 354 and the new remainder 81, and apply the division lemma to get

354 = 81 x 4 + 30

We consider the new divisor 81 and the new remainder 30,and apply the division lemma to get

81 = 30 x 2 + 21

We consider the new divisor 30 and the new remainder 21,and apply the division lemma to get

30 = 21 x 1 + 9

We consider the new divisor 21 and the new remainder 9,and apply the division lemma to get

21 = 9 x 2 + 3

We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get

9 = 3 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 789 and 435 is 3

Notice that 3 = HCF(9,3) = HCF(21,9) = HCF(30,21) = HCF(81,30) = HCF(354,81) = HCF(435,354) = HCF(789,435) .

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

Step 1: Since 379 > 3, we apply the division lemma to 379 and 3, to get

379 = 3 x 126 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 379 is 1

Notice that 1 = HCF(3,1) = HCF(379,3) .
