4/10 of 30 = 30*4/10 = 12
Binary Coded Decimal. It's a modified form of binary. 10 8 4 2 1. When the count gets to 10 the tens column has a 1 in it. 20 10 8 4 2 1. The tens are also arranged in a binary format. It makes the format more compact.
Factors of 4: 1, 2, 4 Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30 Compare. Greatest common factor is 2.
2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30 6: 6, 12, 18, 24, 30 10: 10, 20, 30 LCM = 30
The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The common factors of 30 and 40 are 1, 2, 5, and 10, and the GCF is 10.
I am guessing you want common factors. That is to say factors common to 10 and 30 The common factors would be: 1,2, 5, and 10, but there only 4 that are common. 15 and 30 are factors of 30 so if you add those you have 6 factors.
