HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 985, 648, 488, 743 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 985, 648, 488, 743 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 985, 648, 488, 743 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 985, 648, 488, 743 is 1.

HCF(985, 648, 488, 743) = 1

Highest Common Factor of 985,648,488,743 using Euclid's algorithm

Highest Common Factor of 985,648,488,743 is 1

Step 1: Since 985 > 648, we apply the division lemma to 985 and 648, to get

985 = 648 x 1 + 337

Step 2: Since the reminder 648 ≠ 0, we apply division lemma to 337 and 648, to get

648 = 337 x 1 + 311

Step 3: We consider the new divisor 337 and the new remainder 311, and apply the division lemma to get

337 = 311 x 1 + 26

We consider the new divisor 311 and the new remainder 26,and apply the division lemma to get

311 = 26 x 11 + 25

We consider the new divisor 26 and the new remainder 25,and apply the division lemma to get

26 = 25 x 1 + 1

We consider the new divisor 25 and the new remainder 1,and apply the division lemma to get

25 = 1 x 25 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 985 and 648 is 1

Notice that 1 = HCF(25,1) = HCF(26,25) = HCF(311,26) = HCF(337,311) = HCF(648,337) = HCF(985,648) .

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

Step 1: Since 488 > 1, we apply the division lemma to 488 and 1, to get

488 = 1 x 488 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 488 is 1

Notice that 1 = HCF(488,1) .

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

Step 1: Since 743 > 1, we apply the division lemma to 743 and 1, to get

743 = 1 x 743 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 743 is 1

Notice that 1 = HCF(743,1) .
