HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 784, 537, 644 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 784, 537, 644 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 784, 537, 644 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 784, 537, 644 is 1.

HCF(784, 537, 644) = 1

Highest common factor (HCF) of 784, 537, 644 is 1.

Highest Common Factor of 784,537,644 using Euclid's algorithm

Highest Common Factor of 784,537,644 is 1

Step 1: Since 784 > 537, we apply the division lemma to 784 and 537, to get

784 = 537 x 1 + 247

Step 2: Since the reminder 537 ≠ 0, we apply division lemma to 247 and 537, to get

537 = 247 x 2 + 43

Step 3: We consider the new divisor 247 and the new remainder 43, and apply the division lemma to get

247 = 43 x 5 + 32

We consider the new divisor 43 and the new remainder 32,and apply the division lemma to get

43 = 32 x 1 + 11

We consider the new divisor 32 and the new remainder 11,and apply the division lemma to get

32 = 11 x 2 + 10

We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get

11 = 10 x 1 + 1

We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 784 and 537 is 1

Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(32,11) = HCF(43,32) = HCF(247,43) = HCF(537,247) = HCF(784,537) .

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

Step 1: Since 644 > 1, we apply the division lemma to 644 and 1, to get

644 = 1 x 644 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 644 is 1

Notice that 1 = HCF(644,1) .
