HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 130, 949, 778, 64 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 130, 949, 778, 64 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 130, 949, 778, 64 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 130, 949, 778, 64 is 1.
HCF(130, 949, 778, 64) = 1
HCF of 130, 949, 778, 64 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 130, 949, 778, 64 is 1.
Highest Common Factor of 130,949,778,64 is 1
Step 1: Since 949 > 130, we apply the division lemma to 949 and 130, to get
949 = 130 x 7 + 39
Step 2: Since the reminder 130 ≠ 0, we apply division lemma to 39 and 130, to get
130 = 39 x 3 + 13
Step 3: We consider the new divisor 39 and the new remainder 13, and apply the division lemma to get
39 = 13 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 130 and 949 is 13
Notice that 13 = HCF(39,13) = HCF(130,39) = HCF(949,130) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 778 > 13, we apply the division lemma to 778 and 13, to get
778 = 13 x 59 + 11
Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 11 and 13, to get
13 = 11 x 1 + 2
Step 3: We consider the new divisor 11 and the new remainder 2, and apply the division lemma to get
11 = 2 x 5 + 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 13 and 778 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(778,13) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 64 > 1, we apply the division lemma to 64 and 1, to get
64 = 1 x 64 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 64 is 1
Notice that 1 = HCF(64,1) .
