HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 437, 402, 702 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 437, 402, 702 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 437, 402, 702 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 437, 402, 702 is 1.

HCF(437, 402, 702) = 1

HCF of 437, 402, 702 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 437, 402, 702 is 1.

Highest Common Factor of 437,402,702 using Euclid's algorithm

Highest Common Factor of 437,402,702 is 1

Step 1: Since 437 > 402, we apply the division lemma to 437 and 402, to get

437 = 402 x 1 + 35

Step 2: Since the reminder 402 ≠ 0, we apply division lemma to 35 and 402, to get

402 = 35 x 11 + 17

Step 3: We consider the new divisor 35 and the new remainder 17, and apply the division lemma to get

35 = 17 x 2 + 1

We consider the new divisor 17 and the new remainder 1, and apply the division lemma to get

17 = 1 x 17 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 437 and 402 is 1

Notice that 1 = HCF(17,1) = HCF(35,17) = HCF(402,35) = HCF(437,402) .


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

Step 1: Since 702 > 1, we apply the division lemma to 702 and 1, to get

702 = 1 x 702 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 702 is 1

Notice that 1 = HCF(702,1) .
