Given numbers are 705, 612, 655, 672
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(705, 612) = 143820
GCD(705, 612) = ( 705 x 612 ) / 143820
= 705 / 612
= 705
Step2:
LCM(3, 655) = 1965
GCD(3, 655) = ( 3 x 655 ) / 1965
= 3 / 655
= 3
Step3:
LCM(1, 672) = 672
GCD(1, 672) = ( 1 x 672 ) / 672
= 1 / 672
= 1
So, Greatest Common Divisor of 705, 612, 655, 672 is 1
