HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 288, 455, 822, 616 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 288, 455, 822, 616 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 288, 455, 822, 616 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 288, 455, 822, 616 is 1.

HCF(288, 455, 822, 616) = 1

Highest Common Factor of 288,455,822,616 using Euclid's algorithm

Highest Common Factor of 288,455,822,616 is 1

Step 1: Since 455 > 288, we apply the division lemma to 455 and 288, to get

455 = 288 x 1 + 167

Step 2: Since the reminder 288 ≠ 0, we apply division lemma to 167 and 288, to get

288 = 167 x 1 + 121

Step 3: We consider the new divisor 167 and the new remainder 121, and apply the division lemma to get

167 = 121 x 1 + 46

We consider the new divisor 121 and the new remainder 46,and apply the division lemma to get

121 = 46 x 2 + 29

We consider the new divisor 46 and the new remainder 29,and apply the division lemma to get

46 = 29 x 1 + 17

We consider the new divisor 29 and the new remainder 17,and apply the division lemma to get

29 = 17 x 1 + 12

We consider the new divisor 17 and the new remainder 12,and apply the division lemma to get

17 = 12 x 1 + 5

We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get

12 = 5 x 2 + 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 288 and 455 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(17,12) = HCF(29,17) = HCF(46,29) = HCF(121,46) = HCF(167,121) = HCF(288,167) = HCF(455,288) .

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

Step 1: Since 822 > 1, we apply the division lemma to 822 and 1, to get

822 = 1 x 822 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 822 is 1

Notice that 1 = HCF(822,1) .

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

Step 1: Since 616 > 1, we apply the division lemma to 616 and 1, to get

616 = 1 x 616 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 616 is 1

Notice that 1 = HCF(616,1) .
