HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 541, 749, 642 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 541, 749, 642 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 541, 749, 642 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 541, 749, 642 is 1.

HCF(541, 749, 642) = 1

Highest common factor (HCF) of 541, 749, 642 is 1.

Highest Common Factor of 541,749,642 using Euclid's algorithm

Highest Common Factor of 541,749,642 is 1

Step 1: Since 749 > 541, we apply the division lemma to 749 and 541, to get

749 = 541 x 1 + 208

Step 2: Since the reminder 541 ≠ 0, we apply division lemma to 208 and 541, to get

541 = 208 x 2 + 125

Step 3: We consider the new divisor 208 and the new remainder 125, and apply the division lemma to get

208 = 125 x 1 + 83

We consider the new divisor 125 and the new remainder 83,and apply the division lemma to get

125 = 83 x 1 + 42

We consider the new divisor 83 and the new remainder 42,and apply the division lemma to get

83 = 42 x 1 + 41

We consider the new divisor 42 and the new remainder 41,and apply the division lemma to get

42 = 41 x 1 + 1

We consider the new divisor 41 and the new remainder 1,and apply the division lemma to get

41 = 1 x 41 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 541 and 749 is 1

Notice that 1 = HCF(41,1) = HCF(42,41) = HCF(83,42) = HCF(125,83) = HCF(208,125) = HCF(541,208) = HCF(749,541) .

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

Step 1: Since 642 > 1, we apply the division lemma to 642 and 1, to get

642 = 1 x 642 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 642 is 1

Notice that 1 = HCF(642,1) .
