HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 180, 397, 740 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 180, 397, 740 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 180, 397, 740 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 180, 397, 740 is 1.

HCF(180, 397, 740) = 1

Highest common factor (HCF) of 180, 397, 740 is 1.

Highest Common Factor of 180,397,740 using Euclid's algorithm

Highest Common Factor of 180,397,740 is 1

Step 1: Since 397 > 180, we apply the division lemma to 397 and 180, to get

397 = 180 x 2 + 37

Step 2: Since the reminder 180 ≠ 0, we apply division lemma to 37 and 180, to get

180 = 37 x 4 + 32

Step 3: We consider the new divisor 37 and the new remainder 32, and apply the division lemma to get

37 = 32 x 1 + 5

We consider the new divisor 32 and the new remainder 5,and apply the division lemma to get

32 = 5 x 6 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 180 and 397 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(32,5) = HCF(37,32) = HCF(180,37) = HCF(397,180) .

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

Step 1: Since 740 > 1, we apply the division lemma to 740 and 1, to get

740 = 1 x 740 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 740 is 1

Notice that 1 = HCF(740,1) .
