HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 945, 216, 700 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 945, 216, 700 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 945, 216, 700 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 945, 216, 700 is 1.

HCF(945, 216, 700) = 1

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

HCF of:

Highest common factor (HCF) of 945, 216, 700 is 1.

Highest Common Factor of 945,216,700 using Euclid's algorithm

Highest Common Factor of 945,216,700 is 1

Step 1: Since 945 > 216, we apply the division lemma to 945 and 216, to get

945 = 216 x 4 + 81

Step 2: Since the reminder 216 ≠ 0, we apply division lemma to 81 and 216, to get

216 = 81 x 2 + 54

Step 3: We consider the new divisor 81 and the new remainder 54, and apply the division lemma to get

81 = 54 x 1 + 27

We consider the new divisor 54 and the new remainder 27, and apply the division lemma to get

54 = 27 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 27, the HCF of 945 and 216 is 27

Notice that 27 = HCF(54,27) = HCF(81,54) = HCF(216,81) = HCF(945,216) .

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

Step 1: Since 700 > 27, we apply the division lemma to 700 and 27, to get

700 = 27 x 25 + 25

Step 2: Since the reminder 27 ≠ 0, we apply division lemma to 25 and 27, to get

27 = 25 x 1 + 2

Step 3: We consider the new divisor 25 and the new remainder 2, and apply the division lemma to get

25 = 2 x 12 + 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 27 and 700 is 1

Notice that 1 = HCF(2,1) = HCF(25,2) = HCF(27,25) = HCF(700,27) .
