HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 153, 553, 905 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 153, 553, 905 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 153, 553, 905 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 153, 553, 905 is 1.

HCF(153, 553, 905) = 1

Highest common factor (HCF) of 153, 553, 905 is 1.

Highest Common Factor of 153,553,905 using Euclid's algorithm

Highest Common Factor of 153,553,905 is 1

Step 1: Since 553 > 153, we apply the division lemma to 553 and 153, to get

553 = 153 x 3 + 94

Step 2: Since the reminder 153 ≠ 0, we apply division lemma to 94 and 153, to get

153 = 94 x 1 + 59

Step 3: We consider the new divisor 94 and the new remainder 59, and apply the division lemma to get

94 = 59 x 1 + 35

We consider the new divisor 59 and the new remainder 35,and apply the division lemma to get

59 = 35 x 1 + 24

We consider the new divisor 35 and the new remainder 24,and apply the division lemma to get

35 = 24 x 1 + 11

We consider the new divisor 24 and the new remainder 11,and apply the division lemma to get

24 = 11 x 2 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 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 153 and 553 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(24,11) = HCF(35,24) = HCF(59,35) = HCF(94,59) = HCF(153,94) = HCF(553,153) .

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

Step 1: Since 905 > 1, we apply the division lemma to 905 and 1, to get

905 = 1 x 905 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 905 is 1

Notice that 1 = HCF(905,1) .
