HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 698, 551, 783 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 698, 551, 783 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 698, 551, 783 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 698, 551, 783 is 1.

HCF(698, 551, 783) = 1

HCF of 698, 551, 783 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 698, 551, 783 is 1.

Highest Common Factor of 698,551,783 using Euclid's algorithm

Highest Common Factor of 698,551,783 is 1

Step 1: Since 698 > 551, we apply the division lemma to 698 and 551, to get

698 = 551 x 1 + 147

Step 2: Since the reminder 551 ≠ 0, we apply division lemma to 147 and 551, to get

551 = 147 x 3 + 110

Step 3: We consider the new divisor 147 and the new remainder 110, and apply the division lemma to get

147 = 110 x 1 + 37

We consider the new divisor 110 and the new remainder 37,and apply the division lemma to get

110 = 37 x 2 + 36

We consider the new divisor 37 and the new remainder 36,and apply the division lemma to get

37 = 36 x 1 + 1

We consider the new divisor 36 and the new remainder 1,and apply the division lemma to get

36 = 1 x 36 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 698 and 551 is 1

Notice that 1 = HCF(36,1) = HCF(37,36) = HCF(110,37) = HCF(147,110) = HCF(551,147) = HCF(698,551) .

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

Step 1: Since 783 > 1, we apply the division lemma to 783 and 1, to get

783 = 1 x 783 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 783 is 1

Notice that 1 = HCF(783,1) .
