HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 542, 689, 346 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 542, 689, 346 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, 689, 346 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, 689, 346 is 1.

HCF(542, 689, 346) = 1

Highest common factor (HCF) of 542, 689, 346 is 1.

Highest Common Factor of 542,689,346 using Euclid's algorithm

Highest Common Factor of 542,689,346 is 1

Step 1: Since 689 > 542, we apply the division lemma to 689 and 542, to get

689 = 542 x 1 + 147

Step 2: Since the reminder 542 ≠ 0, we apply division lemma to 147 and 542, to get

542 = 147 x 3 + 101

Step 3: We consider the new divisor 147 and the new remainder 101, and apply the division lemma to get

147 = 101 x 1 + 46

We consider the new divisor 101 and the new remainder 46,and apply the division lemma to get

101 = 46 x 2 + 9

We consider the new divisor 46 and the new remainder 9,and apply the division lemma to get

46 = 9 x 5 + 1

We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 542 and 689 is 1

Notice that 1 = HCF(9,1) = HCF(46,9) = HCF(101,46) = HCF(147,101) = HCF(542,147) = HCF(689,542) .

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

Step 1: Since 346 > 1, we apply the division lemma to 346 and 1, to get

346 = 1 x 346 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 346 is 1

Notice that 1 = HCF(346,1) .
