HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 641, 392, 432 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 641, 392, 432 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 641, 392, 432 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 641, 392, 432 is 1.

HCF(641, 392, 432) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 641, 392, 432 is 1.

Highest Common Factor of 641,392,432 using Euclid's algorithm

Highest Common Factor of 641,392,432 is 1

Step 1: Since 641 > 392, we apply the division lemma to 641 and 392, to get

641 = 392 x 1 + 249

Step 2: Since the reminder 392 ≠ 0, we apply division lemma to 249 and 392, to get

392 = 249 x 1 + 143

Step 3: We consider the new divisor 249 and the new remainder 143, and apply the division lemma to get

249 = 143 x 1 + 106

We consider the new divisor 143 and the new remainder 106,and apply the division lemma to get

143 = 106 x 1 + 37

We consider the new divisor 106 and the new remainder 37,and apply the division lemma to get

106 = 37 x 2 + 32

We consider the new divisor 37 and the new remainder 32,and apply the division lemma to get

37 = 32 x 1 + 5

We consider the new divisor 32 and the new remainder 5,and apply the division lemma to get

32 = 5 x 6 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 641 and 392 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(32,5) = HCF(37,32) = HCF(106,37) = HCF(143,106) = HCF(249,143) = HCF(392,249) = HCF(641,392) .

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

Step 1: Since 432 > 1, we apply the division lemma to 432 and 1, to get

432 = 1 x 432 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 432 is 1

Notice that 1 = HCF(432,1) .
