HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 149, 738, 572 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 149, 738, 572 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 149, 738, 572 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 149, 738, 572 is 1.

HCF(149, 738, 572) = 1

HCF of 149, 738, 572 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 149, 738, 572 is 1.

Highest Common Factor of 149,738,572 using Euclid's algorithm

Highest Common Factor of 149,738,572 is 1

Step 1: Since 738 > 149, we apply the division lemma to 738 and 149, to get

738 = 149 x 4 + 142

Step 2: Since the reminder 149 ≠ 0, we apply division lemma to 142 and 149, to get

149 = 142 x 1 + 7

Step 3: We consider the new divisor 142 and the new remainder 7, and apply the division lemma to get

142 = 7 x 20 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 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 149 and 738 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(142,7) = HCF(149,142) = HCF(738,149) .


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

Step 1: Since 572 > 1, we apply the division lemma to 572 and 1, to get

572 = 1 x 572 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 572 is 1

Notice that 1 = HCF(572,1) .
