HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 945, 837, 437 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 945, 837, 437 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, 837, 437 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, 837, 437 is 1.

HCF(945, 837, 437) = 1

HCF of 945, 837, 437 using Euclid's algorithm

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

Highest common factor (HCF) of 945, 837, 437 is 1.

Highest Common Factor of 945,837,437 using Euclid's algorithm

Highest Common Factor of 945,837,437 is 1

Step 1: Since 945 > 837, we apply the division lemma to 945 and 837, to get

945 = 837 x 1 + 108

Step 2: Since the reminder 837 ≠ 0, we apply division lemma to 108 and 837, to get

837 = 108 x 7 + 81

Step 3: We consider the new divisor 108 and the new remainder 81, and apply the division lemma to get

108 = 81 x 1 + 27

We consider the new divisor 81 and the new remainder 27, and apply the division lemma to get

81 = 27 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 27, the HCF of 945 and 837 is 27

Notice that 27 = HCF(81,27) = HCF(108,81) = HCF(837,108) = HCF(945,837) .

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

Step 1: Since 437 > 27, we apply the division lemma to 437 and 27, to get

437 = 27 x 16 + 5

Step 2: Since the reminder 27 ≠ 0, we apply division lemma to 5 and 27, to get

27 = 5 x 5 + 2

Step 3: 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 27 and 437 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(27,5) = HCF(437,27) .
