HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 148, 961, 670, 664 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 148, 961, 670, 664 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 148, 961, 670, 664 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 148, 961, 670, 664 is 1.

HCF(148, 961, 670, 664) = 1

HCF of 148, 961, 670, 664 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 148, 961, 670, 664 is 1.

Highest Common Factor of 148,961,670,664 using Euclid's algorithm

Highest Common Factor of 148,961,670,664 is 1

Step 1: Since 961 > 148, we apply the division lemma to 961 and 148, to get

961 = 148 x 6 + 73

Step 2: Since the reminder 148 ≠ 0, we apply division lemma to 73 and 148, to get

148 = 73 x 2 + 2

Step 3: We consider the new divisor 73 and the new remainder 2, and apply the division lemma to get

73 = 2 x 36 + 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 148 and 961 is 1

Notice that 1 = HCF(2,1) = HCF(73,2) = HCF(148,73) = HCF(961,148) .


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

Step 1: Since 670 > 1, we apply the division lemma to 670 and 1, to get

670 = 1 x 670 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 670 is 1

Notice that 1 = HCF(670,1) .


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

Step 1: Since 664 > 1, we apply the division lemma to 664 and 1, to get

664 = 1 x 664 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 664 is 1

Notice that 1 = HCF(664,1) .
