HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 918, 4421 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 918, 4421 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 918, 4421 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 918, 4421 is 1.

HCF(918, 4421) = 1

Highest Common Factor of 918,4421 using Euclid's algorithm

Highest Common Factor of 918,4421 is 1

Step 1: Since 4421 > 918, we apply the division lemma to 4421 and 918, to get

4421 = 918 x 4 + 749

Step 2: Since the reminder 918 ≠ 0, we apply division lemma to 749 and 918, to get

918 = 749 x 1 + 169

Step 3: We consider the new divisor 749 and the new remainder 169, and apply the division lemma to get

749 = 169 x 4 + 73

We consider the new divisor 169 and the new remainder 73,and apply the division lemma to get

169 = 73 x 2 + 23

We consider the new divisor 73 and the new remainder 23,and apply the division lemma to get

73 = 23 x 3 + 4

We consider the new divisor 23 and the new remainder 4,and apply the division lemma to get

23 = 4 x 5 + 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 918 and 4421 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(23,4) = HCF(73,23) = HCF(169,73) = HCF(749,169) = HCF(918,749) = HCF(4421,918) .
