Given numbers are 520, 856, 898, 655
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(520, 856) = 55640
GCD(520, 856) = ( 520 x 856 ) / 55640
= 520 / 856
= 520
Step2:
LCM(8, 898) = 3592
GCD(8, 898) = ( 8 x 898 ) / 3592
= 8 / 898
= 8
Step3:
LCM(2, 655) = 1310
GCD(2, 655) = ( 2 x 655 ) / 1310
= 2 / 655
= 2
So, Greatest Common Divisor of 520, 856, 898, 655 is 1
