HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 621, 740, 223 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 621, 740, 223 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 621, 740, 223 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 621, 740, 223 is 1.

HCF(621, 740, 223) = 1

Highest common factor (HCF) of 621, 740, 223 is 1.

Highest Common Factor of 621,740,223 using Euclid's algorithm

Highest Common Factor of 621,740,223 is 1

Step 1: Since 740 > 621, we apply the division lemma to 740 and 621, to get

740 = 621 x 1 + 119

Step 2: Since the reminder 621 ≠ 0, we apply division lemma to 119 and 621, to get

621 = 119 x 5 + 26

Step 3: We consider the new divisor 119 and the new remainder 26, and apply the division lemma to get

119 = 26 x 4 + 15

We consider the new divisor 26 and the new remainder 15,and apply the division lemma to get

26 = 15 x 1 + 11

We consider the new divisor 15 and the new remainder 11,and apply the division lemma to get

15 = 11 x 1 + 4

We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get

11 = 4 x 2 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

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 621 and 740 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(26,15) = HCF(119,26) = HCF(621,119) = HCF(740,621) .

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

Step 1: Since 223 > 1, we apply the division lemma to 223 and 1, to get

223 = 1 x 223 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 223 is 1

Notice that 1 = HCF(223,1) .
