HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 825, 555, 553, 947 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 825, 555, 553, 947 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 825, 555, 553, 947 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 825, 555, 553, 947 is 1.

HCF(825, 555, 553, 947) = 1

HCF of 825, 555, 553, 947 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 825, 555, 553, 947 is 1.

Highest Common Factor of 825,555,553,947 using Euclid's algorithm

Highest Common Factor of 825,555,553,947 is 1

Step 1: Since 825 > 555, we apply the division lemma to 825 and 555, to get

825 = 555 x 1 + 270

Step 2: Since the reminder 555 ≠ 0, we apply division lemma to 270 and 555, to get

555 = 270 x 2 + 15

Step 3: We consider the new divisor 270 and the new remainder 15, and apply the division lemma to get

270 = 15 x 18 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 825 and 555 is 15

Notice that 15 = HCF(270,15) = HCF(555,270) = HCF(825,555) .

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

Step 1: Since 553 > 15, we apply the division lemma to 553 and 15, to get

553 = 15 x 36 + 13

Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 13 and 15, to get

15 = 13 x 1 + 2

Step 3: We consider the new divisor 13 and the new remainder 2, and apply the division lemma to get

13 = 2 x 6 + 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 15 and 553 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(553,15) .

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

Step 1: Since 947 > 1, we apply the division lemma to 947 and 1, to get

947 = 1 x 947 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 947 is 1

Notice that 1 = HCF(947,1) .
