HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 359, 972 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 359, 972 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 359, 972 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 359, 972 is 1.
HCF(359, 972) = 1
HCF of 359, 972 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 359, 972 is 1.
Highest Common Factor of 359,972 is 1
Step 1: Since 972 > 359, we apply the division lemma to 972 and 359, to get
972 = 359 x 2 + 254
Step 2: Since the reminder 359 ≠ 0, we apply division lemma to 254 and 359, to get
359 = 254 x 1 + 105
Step 3: We consider the new divisor 254 and the new remainder 105, and apply the division lemma to get
254 = 105 x 2 + 44
We consider the new divisor 105 and the new remainder 44,and apply the division lemma to get
105 = 44 x 2 + 17
We consider the new divisor 44 and the new remainder 17,and apply the division lemma to get
44 = 17 x 2 + 10
We consider the new divisor 17 and the new remainder 10,and apply the division lemma to get
17 = 10 x 1 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 359 and 972 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(44,17) = HCF(105,44) = HCF(254,105) = HCF(359,254) = HCF(972,359) .
