That would be 1--no numbers besides 1 go into both 10 and 21.
GCD: 21
The Greatest Common Divisor/Denominator is 21
The greatest common divisor (GCD) of 45 and 10 is 5.
Greatest Common Divisor (GCD) for 50 70 is 10.
Greatest Common Divisor (GCD) for 20 30 is 10.
GCD: 3
GCD: 21
The GCF is 3.
60=6*10, 126=6*21, so their gcd is 6.I hope ot is not too late for your homework.
The Greatest Common Divisor/Denominator is 21
The greatest common divisor (GCD) of 45 and 10 is 5.
7
The GCF is 7.
gcd (6, 10) = gcf (6, 10) = hcf (6, 10) = 2 LCM (6, 10) = 30
