HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 356, 545, 22, 219 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 356, 545, 22, 219 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 356, 545, 22, 219 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 356, 545, 22, 219 is 1.

HCF(356, 545, 22, 219) = 1

Highest Common Factor of 356,545,22,219 using Euclid's algorithm

Highest Common Factor of 356,545,22,219 is 1

Step 1: Since 545 > 356, we apply the division lemma to 545 and 356, to get

545 = 356 x 1 + 189

Step 2: Since the reminder 356 ≠ 0, we apply division lemma to 189 and 356, to get

356 = 189 x 1 + 167

Step 3: We consider the new divisor 189 and the new remainder 167, and apply the division lemma to get

189 = 167 x 1 + 22

We consider the new divisor 167 and the new remainder 22,and apply the division lemma to get

167 = 22 x 7 + 13

We consider the new divisor 22 and the new remainder 13,and apply the division lemma to get

22 = 13 x 1 + 9

We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get

13 = 9 x 1 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 356 and 545 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(22,13) = HCF(167,22) = HCF(189,167) = HCF(356,189) = HCF(545,356) .

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

Step 1: Since 22 > 1, we apply the division lemma to 22 and 1, to get

22 = 1 x 22 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 22 is 1

Notice that 1 = HCF(22,1) .

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

Step 1: Since 219 > 1, we apply the division lemma to 219 and 1, to get

219 = 1 x 219 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 219 is 1

Notice that 1 = HCF(219,1) .
