Given numbers are 270, 213, 159, 780
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(270, 213) = 19170
GCD(270, 213) = ( 270 x 213 ) / 19170
= 270 / 213
= 270
Step2:
LCM(3, 159) = 159
GCD(3, 159) = ( 3 x 159 ) / 159
= 3 / 159
= 3
Step3:
LCM(3, 780) = 780
GCD(3, 780) = ( 3 x 780 ) / 780
= 3 / 780
= 3
So, Greatest Common Divisor of 270, 213, 159, 780 is 3
