HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 720, 975, 893, 647 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 720, 975, 893, 647 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 720, 975, 893, 647 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 720, 975, 893, 647 is 1.
HCF(720, 975, 893, 647) = 1
HCF of 720, 975, 893, 647 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 720, 975, 893, 647 is 1.
Highest Common Factor of 720,975,893,647 is 1
Step 1: Since 975 > 720, we apply the division lemma to 975 and 720, to get
975 = 720 x 1 + 255
Step 2: Since the reminder 720 ≠ 0, we apply division lemma to 255 and 720, to get
720 = 255 x 2 + 210
Step 3: We consider the new divisor 255 and the new remainder 210, and apply the division lemma to get
255 = 210 x 1 + 45
We consider the new divisor 210 and the new remainder 45,and apply the division lemma to get
210 = 45 x 4 + 30
We consider the new divisor 45 and the new remainder 30,and apply the division lemma to get
45 = 30 x 1 + 15
We consider the new divisor 30 and the new remainder 15,and apply the division lemma to get
30 = 15 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 720 and 975 is 15
Notice that 15 = HCF(30,15) = HCF(45,30) = HCF(210,45) = HCF(255,210) = HCF(720,255) = HCF(975,720) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 893 > 15, we apply the division lemma to 893 and 15, to get
893 = 15 x 59 + 8
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 8 and 15, to get
15 = 8 x 1 + 7
Step 3: We consider the new divisor 8 and the new remainder 7, and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1, and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 15 and 893 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(893,15) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 647 > 1, we apply the division lemma to 647 and 1, to get
647 = 1 x 647 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 647 is 1
Notice that 1 = HCF(647,1) .
