Given numbers are 215, 747, 530, 346
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(215, 747) = 160605
GCD(215, 747) = ( 215 x 747 ) / 160605
= 215 / 747
= 215
Step2:
LCM(1, 530) = 530
GCD(1, 530) = ( 1 x 530 ) / 530
= 1 / 530
= 1
Step3:
LCM(1, 346) = 346
GCD(1, 346) = ( 1 x 346 ) / 346
= 1 / 346
= 1
So, Greatest Common Divisor of 215, 747, 530, 346 is 1
