Given numbers are 676, 742, 785, 215
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(676, 742) = 250796
GCD(676, 742) = ( 676 x 742 ) / 250796
= 676 / 742
= 676
Step2:
LCM(2, 785) = 1570
GCD(2, 785) = ( 2 x 785 ) / 1570
= 2 / 785
= 2
Step3:
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
= 1 / 215
= 1
So, Greatest Common Divisor of 676, 742, 785, 215 is 1
