HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 802, 639, 845, 406 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 802, 639, 845, 406 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 802, 639, 845, 406 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 802, 639, 845, 406 is 1.

HCF(802, 639, 845, 406) = 1

Highest Common Factor of 802,639,845,406 using Euclid's algorithm

Highest Common Factor of 802,639,845,406 is 1

Step 1: Since 802 > 639, we apply the division lemma to 802 and 639, to get

802 = 639 x 1 + 163

Step 2: Since the reminder 639 ≠ 0, we apply division lemma to 163 and 639, to get

639 = 163 x 3 + 150

Step 3: We consider the new divisor 163 and the new remainder 150, and apply the division lemma to get

163 = 150 x 1 + 13

We consider the new divisor 150 and the new remainder 13,and apply the division lemma to get

150 = 13 x 11 + 7

We consider the new divisor 13 and the new remainder 7,and apply the division lemma to get

13 = 7 x 1 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 802 and 639 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(13,7) = HCF(150,13) = HCF(163,150) = HCF(639,163) = HCF(802,639) .

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

Step 1: Since 845 > 1, we apply the division lemma to 845 and 1, to get

845 = 1 x 845 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 845 is 1

Notice that 1 = HCF(845,1) .

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

Step 1: Since 406 > 1, we apply the division lemma to 406 and 1, to get

406 = 1 x 406 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 406 is 1

Notice that 1 = HCF(406,1) .
