HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 743, 609, 953 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 743, 609, 953 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 743, 609, 953 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 743, 609, 953 is 1.

HCF(743, 609, 953) = 1

Highest common factor (HCF) of 743, 609, 953 is 1.

Highest Common Factor of 743,609,953 using Euclid's algorithm

Highest Common Factor of 743,609,953 is 1

Step 1: Since 743 > 609, we apply the division lemma to 743 and 609, to get

743 = 609 x 1 + 134

Step 2: Since the reminder 609 ≠ 0, we apply division lemma to 134 and 609, to get

609 = 134 x 4 + 73

Step 3: We consider the new divisor 134 and the new remainder 73, and apply the division lemma to get

134 = 73 x 1 + 61

We consider the new divisor 73 and the new remainder 61,and apply the division lemma to get

73 = 61 x 1 + 12

We consider the new divisor 61 and the new remainder 12,and apply the division lemma to get

61 = 12 x 5 + 1

We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get

12 = 1 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 743 and 609 is 1

Notice that 1 = HCF(12,1) = HCF(61,12) = HCF(73,61) = HCF(134,73) = HCF(609,134) = HCF(743,609) .


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

Step 1: Since 953 > 1, we apply the division lemma to 953 and 1, to get

953 = 1 x 953 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 953 is 1

Notice that 1 = HCF(953,1) .
