HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 507, 770, 308, 19 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 507, 770, 308, 19 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 507, 770, 308, 19 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 507, 770, 308, 19 is 1.

HCF(507, 770, 308, 19) = 1

Highest Common Factor of 507,770,308,19 using Euclid's algorithm

Highest Common Factor of 507,770,308,19 is 1

Step 1: Since 770 > 507, we apply the division lemma to 770 and 507, to get

770 = 507 x 1 + 263

Step 2: Since the reminder 507 ≠ 0, we apply division lemma to 263 and 507, to get

507 = 263 x 1 + 244

Step 3: We consider the new divisor 263 and the new remainder 244, and apply the division lemma to get

263 = 244 x 1 + 19

We consider the new divisor 244 and the new remainder 19,and apply the division lemma to get

244 = 19 x 12 + 16

We consider the new divisor 19 and the new remainder 16,and apply the division lemma to get

19 = 16 x 1 + 3

We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get

16 = 3 x 5 + 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 507 and 770 is 1

Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(19,16) = HCF(244,19) = HCF(263,244) = HCF(507,263) = HCF(770,507) .

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

Step 1: Since 308 > 1, we apply the division lemma to 308 and 1, to get

308 = 1 x 308 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 308 is 1

Notice that 1 = HCF(308,1) .

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

Step 1: Since 19 > 1, we apply the division lemma to 19 and 1, to get

19 = 1 x 19 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 19 is 1

Notice that 1 = HCF(19,1) .
