HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 649, 908, 572, 756 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 649, 908, 572, 756 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 649, 908, 572, 756 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 649, 908, 572, 756 is 1.
HCF(649, 908, 572, 756) = 1
HCF of 649, 908, 572, 756 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 649, 908, 572, 756 is 1.
Highest Common Factor of 649,908,572,756 is 1
Step 1: Since 908 > 649, we apply the division lemma to 908 and 649, to get
908 = 649 x 1 + 259
Step 2: Since the reminder 649 ≠ 0, we apply division lemma to 259 and 649, to get
649 = 259 x 2 + 131
Step 3: We consider the new divisor 259 and the new remainder 131, and apply the division lemma to get
259 = 131 x 1 + 128
We consider the new divisor 131 and the new remainder 128,and apply the division lemma to get
131 = 128 x 1 + 3
We consider the new divisor 128 and the new remainder 3,and apply the division lemma to get
128 = 3 x 42 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 649 and 908 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(128,3) = HCF(131,128) = HCF(259,131) = HCF(649,259) = HCF(908,649) .
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) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 756 > 1, we apply the division lemma to 756 and 1, to get
756 = 1 x 756 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 756 is 1
Notice that 1 = HCF(756,1) .
