HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 43, 669, 902 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 43, 669, 902 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 43, 669, 902 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 43, 669, 902 is 1.

HCF(43, 669, 902) = 1

Highest common factor (HCF) of 43, 669, 902 is 1.

Highest Common Factor of 43,669,902 using Euclid's algorithm

Highest Common Factor of 43,669,902 is 1

Step 1: Since 669 > 43, we apply the division lemma to 669 and 43, to get

669 = 43 x 15 + 24

Step 2: Since the reminder 43 ≠ 0, we apply division lemma to 24 and 43, to get

43 = 24 x 1 + 19

Step 3: We consider the new divisor 24 and the new remainder 19, and apply the division lemma to get

24 = 19 x 1 + 5

We consider the new divisor 19 and the new remainder 5,and apply the division lemma to get

19 = 5 x 3 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 43 and 669 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(19,5) = HCF(24,19) = HCF(43,24) = HCF(669,43) .


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

Step 1: Since 902 > 1, we apply the division lemma to 902 and 1, to get

902 = 1 x 902 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 902 is 1

Notice that 1 = HCF(902,1) .
