HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 429, 960, 989, 90 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 429, 960, 989, 90 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 429, 960, 989, 90 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 429, 960, 989, 90 is 1.

HCF(429, 960, 989, 90) = 1

Highest common factor (HCF) of 429, 960, 989, 90 is 1.

Highest Common Factor of 429,960,989,90 using Euclid's algorithm

Highest Common Factor of 429,960,989,90 is 1

Step 1: Since 960 > 429, we apply the division lemma to 960 and 429, to get

960 = 429 x 2 + 102

Step 2: Since the reminder 429 ≠ 0, we apply division lemma to 102 and 429, to get

429 = 102 x 4 + 21

Step 3: We consider the new divisor 102 and the new remainder 21, and apply the division lemma to get

102 = 21 x 4 + 18

We consider the new divisor 21 and the new remainder 18,and apply the division lemma to get

21 = 18 x 1 + 3

We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get

18 = 3 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 429 and 960 is 3

Notice that 3 = HCF(18,3) = HCF(21,18) = HCF(102,21) = HCF(429,102) = HCF(960,429) .


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

Step 1: Since 989 > 3, we apply the division lemma to 989 and 3, to get

989 = 3 x 329 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: 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 3 and 989 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(989,3) .


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

Step 1: Since 90 > 1, we apply the division lemma to 90 and 1, to get

90 = 1 x 90 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 90 is 1

Notice that 1 = HCF(90,1) .
