HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 782, 603, 54 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 782, 603, 54 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 782, 603, 54 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 782, 603, 54 is 1.

HCF(782, 603, 54) = 1

Highest common factor (HCF) of 782, 603, 54 is 1.

Highest Common Factor of 782,603,54 using Euclid's algorithm

Highest Common Factor of 782,603,54 is 1

Step 1: Since 782 > 603, we apply the division lemma to 782 and 603, to get

782 = 603 x 1 + 179

Step 2: Since the reminder 603 ≠ 0, we apply division lemma to 179 and 603, to get

603 = 179 x 3 + 66

Step 3: We consider the new divisor 179 and the new remainder 66, and apply the division lemma to get

179 = 66 x 2 + 47

We consider the new divisor 66 and the new remainder 47,and apply the division lemma to get

66 = 47 x 1 + 19

We consider the new divisor 47 and the new remainder 19,and apply the division lemma to get

47 = 19 x 2 + 9

We consider the new divisor 19 and the new remainder 9,and apply the division lemma to get

19 = 9 x 2 + 1

We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 782 and 603 is 1

Notice that 1 = HCF(9,1) = HCF(19,9) = HCF(47,19) = HCF(66,47) = HCF(179,66) = HCF(603,179) = HCF(782,603) .

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

Step 1: Since 54 > 1, we apply the division lemma to 54 and 1, to get

54 = 1 x 54 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 54 is 1

Notice that 1 = HCF(54,1) .
