HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 509, 774, 754, 393 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 509, 774, 754, 393 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 509, 774, 754, 393 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 509, 774, 754, 393 is 1.

HCF(509, 774, 754, 393) = 1

Highest Common Factor of 509,774,754,393 using Euclid's algorithm

Highest Common Factor of 509,774,754,393 is 1

Step 1: Since 774 > 509, we apply the division lemma to 774 and 509, to get

774 = 509 x 1 + 265

Step 2: Since the reminder 509 ≠ 0, we apply division lemma to 265 and 509, to get

509 = 265 x 1 + 244

Step 3: We consider the new divisor 265 and the new remainder 244, and apply the division lemma to get

265 = 244 x 1 + 21

We consider the new divisor 244 and the new remainder 21,and apply the division lemma to get

244 = 21 x 11 + 13

We consider the new divisor 21 and the new remainder 13,and apply the division lemma to get

21 = 13 x 1 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 509 and 774 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(21,13) = HCF(244,21) = HCF(265,244) = HCF(509,265) = HCF(774,509) .

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

Step 1: Since 754 > 1, we apply the division lemma to 754 and 1, to get

754 = 1 x 754 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 754 is 1

Notice that 1 = HCF(754,1) .

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

Step 1: Since 393 > 1, we apply the division lemma to 393 and 1, to get

393 = 1 x 393 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 393 is 1

Notice that 1 = HCF(393,1) .
