HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 543, 770 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 543, 770 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 543, 770 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 543, 770 is 1.

HCF(543, 770) = 1

Highest common factor (HCF) of 543, 770 is 1.

Highest Common Factor of 543,770 using Euclid's algorithm

Highest Common Factor of 543,770 is 1

Step 1: Since 770 > 543, we apply the division lemma to 770 and 543, to get

770 = 543 x 1 + 227

Step 2: Since the reminder 543 ≠ 0, we apply division lemma to 227 and 543, to get

543 = 227 x 2 + 89

Step 3: We consider the new divisor 227 and the new remainder 89, and apply the division lemma to get

227 = 89 x 2 + 49

We consider the new divisor 89 and the new remainder 49,and apply the division lemma to get

89 = 49 x 1 + 40

We consider the new divisor 49 and the new remainder 40,and apply the division lemma to get

49 = 40 x 1 + 9

We consider the new divisor 40 and the new remainder 9,and apply the division lemma to get

40 = 9 x 4 + 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 543 and 770 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(40,9) = HCF(49,40) = HCF(89,49) = HCF(227,89) = HCF(543,227) = HCF(770,543) .
