Given numbers are 105, 507, 868, 343
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 507) = 17745
GCD(105, 507) = ( 105 x 507 ) / 17745
= 105 / 507
= 105
Step2:
LCM(3, 868) = 2604
GCD(3, 868) = ( 3 x 868 ) / 2604
= 3 / 868
= 3
Step3:
LCM(1, 343) = 343
GCD(1, 343) = ( 1 x 343 ) / 343
= 1 / 343
= 1
So, Greatest Common Divisor of 105, 507, 868, 343 is 1
