HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 400, 730, 972, 511 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 400, 730, 972, 511 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 400, 730, 972, 511 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 400, 730, 972, 511 is 1.
HCF(400, 730, 972, 511) = 1
HCF of 400, 730, 972, 511 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 400, 730, 972, 511 is 1.
Highest Common Factor of 400,730,972,511 is 1
Step 1: Since 730 > 400, we apply the division lemma to 730 and 400, to get
730 = 400 x 1 + 330
Step 2: Since the reminder 400 ≠ 0, we apply division lemma to 330 and 400, to get
400 = 330 x 1 + 70
Step 3: We consider the new divisor 330 and the new remainder 70, and apply the division lemma to get
330 = 70 x 4 + 50
We consider the new divisor 70 and the new remainder 50,and apply the division lemma to get
70 = 50 x 1 + 20
We consider the new divisor 50 and the new remainder 20,and apply the division lemma to get
50 = 20 x 2 + 10
We consider the new divisor 20 and the new remainder 10,and apply the division lemma to get
20 = 10 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 400 and 730 is 10
Notice that 10 = HCF(20,10) = HCF(50,20) = HCF(70,50) = HCF(330,70) = HCF(400,330) = HCF(730,400) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 972 > 10, we apply the division lemma to 972 and 10, to get
972 = 10 x 97 + 2
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 2 and 10, to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 10 and 972 is 2
Notice that 2 = HCF(10,2) = HCF(972,10) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 511 > 2, we apply the division lemma to 511 and 2, to get
511 = 2 x 255 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 511 is 1
Notice that 1 = HCF(2,1) = HCF(511,2) .
