HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 756, 128, 769, 19 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 756, 128, 769, 19 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 756, 128, 769, 19 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 756, 128, 769, 19 is 1.
HCF(756, 128, 769, 19) = 1
HCF of 756, 128, 769, 19 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 756, 128, 769, 19 is 1.
Highest Common Factor of 756,128,769,19 is 1
Step 1: Since 756 > 128, we apply the division lemma to 756 and 128, to get
756 = 128 x 5 + 116
Step 2: Since the reminder 128 ≠ 0, we apply division lemma to 116 and 128, to get
128 = 116 x 1 + 12
Step 3: We consider the new divisor 116 and the new remainder 12, and apply the division lemma to get
116 = 12 x 9 + 8
We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get
12 = 8 x 1 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 756 and 128 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(116,12) = HCF(128,116) = HCF(756,128) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 769 > 4, we apply the division lemma to 769 and 4, to get
769 = 4 x 192 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 769 is 1
Notice that 1 = HCF(4,1) = HCF(769,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 19 > 1, we apply the division lemma to 19 and 1, to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 19 is 1
Notice that 1 = HCF(19,1) .
