The lowest common denominator of any two or more whole numbers, such as 56 and 70, will always be one (1) because 'common denominator' refers to the denominators of two or more fractions or mixed numbers, not whole numbers. So, a set of whole numbers (x,x) would have to be converted to their fraction equivalents, i.e., x/1, which will always yield a denominator of 1.
70=2*5*756=2*2*2*72*7=14
14, 28, 42, 56, 70....

The greatest common factor (GCF) of 56 and 70 is 14.
It is 70
560
the lowest common denominator is 70 the numerators would become 63 and 30
LCD(70, 105) = 210.
70 would be the lowest common denominator
lowest common denominator= 70 therefore; 5/7 + 7/10 = 50/70 + 49/ 70 = 99/70= 1 and 29/70 5/7 - 7/10 = 50/70 - 49/70 = 1/70
The lowest common factor of any set of numbers is 1.
70=2*5*756=2*2*2*72*7=14
14, 28, 42, 56, 70....
The LCD of 5/7 and 7/10 is 70.
A common denominator is 70.
The greatest common factor of 56 & 70 is 14
the answer is 70
