HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 542, 839, 639 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 542, 839, 639 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 542, 839, 639 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 542, 839, 639 is 1.

HCF(542, 839, 639) = 1

HCF of 542, 839, 639 using Euclid's algorithm

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

Highest common factor (HCF) of 542, 839, 639 is 1.

Highest Common Factor of 542,839,639 using Euclid's algorithm

Highest Common Factor of 542,839,639 is 1

Step 1: Since 839 > 542, we apply the division lemma to 839 and 542, to get

839 = 542 x 1 + 297

Step 2: Since the reminder 542 ≠ 0, we apply division lemma to 297 and 542, to get

542 = 297 x 1 + 245

Step 3: We consider the new divisor 297 and the new remainder 245, and apply the division lemma to get

297 = 245 x 1 + 52

We consider the new divisor 245 and the new remainder 52,and apply the division lemma to get

245 = 52 x 4 + 37

We consider the new divisor 52 and the new remainder 37,and apply the division lemma to get

52 = 37 x 1 + 15

We consider the new divisor 37 and the new remainder 15,and apply the division lemma to get

37 = 15 x 2 + 7

We consider the new divisor 15 and the new remainder 7,and apply the division lemma to get

15 = 7 x 2 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 542 and 839 is 1

Notice that 1 = HCF(7,1) = HCF(15,7) = HCF(37,15) = HCF(52,37) = HCF(245,52) = HCF(297,245) = HCF(542,297) = HCF(839,542) .

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

Step 1: Since 639 > 1, we apply the division lemma to 639 and 1, to get

639 = 1 x 639 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 639 is 1

Notice that 1 = HCF(639,1) .
