HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 162, 405, 927, 900 i.e. 9 the largest integer that leaves a remainder zero for all numbers.

HCF of 162, 405, 927, 900 is 9 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 162, 405, 927, 900 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 162, 405, 927, 900 is 9.

HCF(162, 405, 927, 900) = 9

## HCF of 162, 405, 927, 900 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 162, 405, 927, 900 is 9. ### Highest Common Factor of 162,405,927,900 is 9

Step 1: Since 405 > 162, we apply the division lemma to 405 and 162, to get

405 = 162 x 2 + 81

Step 2: Since the reminder 162 ≠ 0, we apply division lemma to 81 and 162, to get

162 = 81 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 81, the HCF of 162 and 405 is 81

Notice that 81 = HCF(162,81) = HCF(405,162) .

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

Step 1: Since 927 > 81, we apply the division lemma to 927 and 81, to get

927 = 81 x 11 + 36

Step 2: Since the reminder 81 ≠ 0, we apply division lemma to 36 and 81, to get

81 = 36 x 2 + 9

Step 3: We consider the new divisor 36 and the new remainder 9, and apply the division lemma to get

36 = 9 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 81 and 927 is 9

Notice that 9 = HCF(36,9) = HCF(81,36) = HCF(927,81) .

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

Step 1: Since 900 > 9, we apply the division lemma to 900 and 9, to get

900 = 9 x 100 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 9 and 900 is 9

Notice that 9 = HCF(900,9) .
