HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 544, 756, 80, 355 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 544, 756, 80, 355 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 544, 756, 80, 355 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 544, 756, 80, 355 is 1.

HCF(544, 756, 80, 355) = 1

Highest Common Factor of 544,756,80,355 using Euclid's algorithm

Highest Common Factor of 544,756,80,355 is 1

Step 1: Since 756 > 544, we apply the division lemma to 756 and 544, to get

756 = 544 x 1 + 212

Step 2: Since the reminder 544 ≠ 0, we apply division lemma to 212 and 544, to get

544 = 212 x 2 + 120

Step 3: We consider the new divisor 212 and the new remainder 120, and apply the division lemma to get

212 = 120 x 1 + 92

We consider the new divisor 120 and the new remainder 92,and apply the division lemma to get

120 = 92 x 1 + 28

We consider the new divisor 92 and the new remainder 28,and apply the division lemma to get

92 = 28 x 3 + 8

We consider the new divisor 28 and the new remainder 8,and apply the division lemma to get

28 = 8 x 3 + 4

We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get

8 = 4 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 544 and 756 is 4

Notice that 4 = HCF(8,4) = HCF(28,8) = HCF(92,28) = HCF(120,92) = HCF(212,120) = HCF(544,212) = HCF(756,544) .

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

Step 1: Since 80 > 4, we apply the division lemma to 80 and 4, to get

80 = 4 x 20 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 80 is 4

Notice that 4 = HCF(80,4) .

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

Step 1: Since 355 > 4, we apply the division lemma to 355 and 4, to get

355 = 4 x 88 + 3

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get

4 = 3 x 1 + 1

Step 3: 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 4 and 355 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(355,4) .
