HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 542, 355, 524 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 542, 355, 524 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, 355, 524 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, 355, 524 is 1.

HCF(542, 355, 524) = 1

Highest common factor (HCF) of 542, 355, 524 is 1.

Highest Common Factor of 542,355,524 using Euclid's algorithm

Highest Common Factor of 542,355,524 is 1

Step 1: Since 542 > 355, we apply the division lemma to 542 and 355, to get

542 = 355 x 1 + 187

Step 2: Since the reminder 355 ≠ 0, we apply division lemma to 187 and 355, to get

355 = 187 x 1 + 168

Step 3: We consider the new divisor 187 and the new remainder 168, and apply the division lemma to get

187 = 168 x 1 + 19

We consider the new divisor 168 and the new remainder 19,and apply the division lemma to get

168 = 19 x 8 + 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 542 and 355 is 1

Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(19,16) = HCF(168,19) = HCF(187,168) = HCF(355,187) = HCF(542,355) .

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

Step 1: Since 524 > 1, we apply the division lemma to 524 and 1, to get

524 = 1 x 524 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 524 is 1

Notice that 1 = HCF(524,1) .
