HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 226, 370, 661 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 226, 370, 661 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 226, 370, 661 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 226, 370, 661 is 1.

HCF(226, 370, 661) = 1

Highest common factor (HCF) of 226, 370, 661 is 1.

Highest Common Factor of 226,370,661 using Euclid's algorithm

Highest Common Factor of 226,370,661 is 1

Step 1: Since 370 > 226, we apply the division lemma to 370 and 226, to get

370 = 226 x 1 + 144

Step 2: Since the reminder 226 ≠ 0, we apply division lemma to 144 and 226, to get

226 = 144 x 1 + 82

Step 3: We consider the new divisor 144 and the new remainder 82, and apply the division lemma to get

144 = 82 x 1 + 62

We consider the new divisor 82 and the new remainder 62,and apply the division lemma to get

82 = 62 x 1 + 20

We consider the new divisor 62 and the new remainder 20,and apply the division lemma to get

62 = 20 x 3 + 2

We consider the new divisor 20 and the new remainder 2,and apply the division lemma to get

20 = 2 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 226 and 370 is 2

Notice that 2 = HCF(20,2) = HCF(62,20) = HCF(82,62) = HCF(144,82) = HCF(226,144) = HCF(370,226) .

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

Step 1: Since 661 > 2, we apply the division lemma to 661 and 2, to get

661 = 2 x 330 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 661 is 1

Notice that 1 = HCF(2,1) = HCF(661,2) .
