Given numbers are 905, 855, 715, 742
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(905, 855) = 154755
GCD(905, 855) = ( 905 x 855 ) / 154755
= 905 / 855
= 905
Step2:
LCM(5, 715) = 715
GCD(5, 715) = ( 5 x 715 ) / 715
= 5 / 715
= 5
Step3:
LCM(5, 742) = 3710
GCD(5, 742) = ( 5 x 742 ) / 3710
= 5 / 742
= 5
So, Greatest Common Divisor of 905, 855, 715, 742 is 1
