HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 603, 991, 923, 86 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 603, 991, 923, 86 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 603, 991, 923, 86 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 603, 991, 923, 86 is 1.

HCF(603, 991, 923, 86) = 1

Highest common factor (HCF) of 603, 991, 923, 86 is 1.

Highest Common Factor of 603,991,923,86 using Euclid's algorithm

Highest Common Factor of 603,991,923,86 is 1

Step 1: Since 991 > 603, we apply the division lemma to 991 and 603, to get

991 = 603 x 1 + 388

Step 2: Since the reminder 603 ≠ 0, we apply division lemma to 388 and 603, to get

603 = 388 x 1 + 215

Step 3: We consider the new divisor 388 and the new remainder 215, and apply the division lemma to get

388 = 215 x 1 + 173

We consider the new divisor 215 and the new remainder 173,and apply the division lemma to get

215 = 173 x 1 + 42

We consider the new divisor 173 and the new remainder 42,and apply the division lemma to get

173 = 42 x 4 + 5

We consider the new divisor 42 and the new remainder 5,and apply the division lemma to get

42 = 5 x 8 + 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 603 and 991 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(42,5) = HCF(173,42) = HCF(215,173) = HCF(388,215) = HCF(603,388) = HCF(991,603) .


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

Step 1: Since 923 > 1, we apply the division lemma to 923 and 1, to get

923 = 1 x 923 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 923 is 1

Notice that 1 = HCF(923,1) .


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

Step 1: Since 86 > 1, we apply the division lemma to 86 and 1, to get

86 = 1 x 86 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 86 is 1

Notice that 1 = HCF(86,1) .
