Given numbers are 530, 806, 387, 705
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(530, 806) = 213590
GCD(530, 806) = ( 530 x 806 ) / 213590
= 530 / 806
= 530
Step2:
LCM(2, 387) = 774
GCD(2, 387) = ( 2 x 387 ) / 774
= 2 / 387
= 2
Step3:
LCM(1, 705) = 705
GCD(1, 705) = ( 1 x 705 ) / 705
= 1 / 705
= 1
So, Greatest Common Divisor of 530, 806, 387, 705 is 1
