HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 434, 1431 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 434, 1431 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 434, 1431 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 434, 1431 is 1.

HCF(434, 1431) = 1

Highest common factor (HCF) of 434, 1431 is 1.

Highest Common Factor of 434,1431 using Euclid's algorithm

Highest Common Factor of 434,1431 is 1

Step 1: Since 1431 > 434, we apply the division lemma to 1431 and 434, to get

1431 = 434 x 3 + 129

Step 2: Since the reminder 434 ≠ 0, we apply division lemma to 129 and 434, to get

434 = 129 x 3 + 47

Step 3: We consider the new divisor 129 and the new remainder 47, and apply the division lemma to get

129 = 47 x 2 + 35

We consider the new divisor 47 and the new remainder 35,and apply the division lemma to get

47 = 35 x 1 + 12

We consider the new divisor 35 and the new remainder 12,and apply the division lemma to get

35 = 12 x 2 + 11

We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get

12 = 11 x 1 + 1

We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get

11 = 1 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 434 and 1431 is 1

Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(35,12) = HCF(47,35) = HCF(129,47) = HCF(434,129) = HCF(1431,434) .
