HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 878, 972, 755 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 878, 972, 755 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 878, 972, 755 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 878, 972, 755 is 1.
HCF(878, 972, 755) = 1
HCF of 878, 972, 755 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 878, 972, 755 is 1.
Highest Common Factor of 878,972,755 is 1
Step 1: Since 972 > 878, we apply the division lemma to 972 and 878, to get
972 = 878 x 1 + 94
Step 2: Since the reminder 878 ≠ 0, we apply division lemma to 94 and 878, to get
878 = 94 x 9 + 32
Step 3: We consider the new divisor 94 and the new remainder 32, and apply the division lemma to get
94 = 32 x 2 + 30
We consider the new divisor 32 and the new remainder 30,and apply the division lemma to get
32 = 30 x 1 + 2
We consider the new divisor 30 and the new remainder 2,and apply the division lemma to get
30 = 2 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 878 and 972 is 2
Notice that 2 = HCF(30,2) = HCF(32,30) = HCF(94,32) = HCF(878,94) = HCF(972,878) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 755 > 2, we apply the division lemma to 755 and 2, to get
755 = 2 x 377 + 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 755 is 1
Notice that 1 = HCF(2,1) = HCF(755,2) .
