HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 378, 545 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 378, 545 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 378, 545 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 378, 545 is 1.

HCF(378, 545) = 1

Highest common factor (HCF) of 378, 545 is 1.

Highest Common Factor of 378,545 using Euclid's algorithm

Highest Common Factor of 378,545 is 1

Step 1: Since 545 > 378, we apply the division lemma to 545 and 378, to get

545 = 378 x 1 + 167

Step 2: Since the reminder 378 ≠ 0, we apply division lemma to 167 and 378, to get

378 = 167 x 2 + 44

Step 3: We consider the new divisor 167 and the new remainder 44, and apply the division lemma to get

167 = 44 x 3 + 35

We consider the new divisor 44 and the new remainder 35,and apply the division lemma to get

44 = 35 x 1 + 9

We consider the new divisor 35 and the new remainder 9,and apply the division lemma to get

35 = 9 x 3 + 8

We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get

9 = 8 x 1 + 1

We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get

8 = 1 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 378 and 545 is 1

Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(35,9) = HCF(44,35) = HCF(167,44) = HCF(378,167) = HCF(545,378) .
