HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 432, 685, 460, 985 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 432, 685, 460, 985 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 432, 685, 460, 985 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 432, 685, 460, 985 is 1.

HCF(432, 685, 460, 985) = 1

Highest Common Factor of 432,685,460,985 using Euclid's algorithm

Highest Common Factor of 432,685,460,985 is 1

Step 1: Since 685 > 432, we apply the division lemma to 685 and 432, to get

685 = 432 x 1 + 253

Step 2: Since the reminder 432 ≠ 0, we apply division lemma to 253 and 432, to get

432 = 253 x 1 + 179

Step 3: We consider the new divisor 253 and the new remainder 179, and apply the division lemma to get

253 = 179 x 1 + 74

We consider the new divisor 179 and the new remainder 74,and apply the division lemma to get

179 = 74 x 2 + 31

We consider the new divisor 74 and the new remainder 31,and apply the division lemma to get

74 = 31 x 2 + 12

We consider the new divisor 31 and the new remainder 12,and apply the division lemma to get

31 = 12 x 2 + 7

We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get

12 = 7 x 1 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 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 432 and 685 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(31,12) = HCF(74,31) = HCF(179,74) = HCF(253,179) = HCF(432,253) = HCF(685,432) .

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

Step 1: Since 460 > 1, we apply the division lemma to 460 and 1, to get

460 = 1 x 460 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 460 is 1

Notice that 1 = HCF(460,1) .

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

Step 1: Since 985 > 1, we apply the division lemma to 985 and 1, to get

985 = 1 x 985 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 985 is 1

Notice that 1 = HCF(985,1) .
