HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 123, 454, 554, 139 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 123, 454, 554, 139 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 123, 454, 554, 139 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 123, 454, 554, 139 is 1.

HCF(123, 454, 554, 139) = 1

Highest Common Factor of 123,454,554,139 using Euclid's algorithm

Highest Common Factor of 123,454,554,139 is 1

Step 1: Since 454 > 123, we apply the division lemma to 454 and 123, to get

454 = 123 x 3 + 85

Step 2: Since the reminder 123 ≠ 0, we apply division lemma to 85 and 123, to get

123 = 85 x 1 + 38

Step 3: We consider the new divisor 85 and the new remainder 38, and apply the division lemma to get

85 = 38 x 2 + 9

We consider the new divisor 38 and the new remainder 9,and apply the division lemma to get

38 = 9 x 4 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 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 123 and 454 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(38,9) = HCF(85,38) = HCF(123,85) = HCF(454,123) .


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

Step 1: Since 554 > 1, we apply the division lemma to 554 and 1, to get

554 = 1 x 554 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 554 is 1

Notice that 1 = HCF(554,1) .


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

Step 1: Since 139 > 1, we apply the division lemma to 139 and 1, to get

139 = 1 x 139 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 139 is 1

Notice that 1 = HCF(139,1) .
