Given numbers are 438, 193, 430, 533
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 193) = 84534
GCD(438, 193) = ( 438 x 193 ) / 84534
= 438 / 193
= 438
Step2:
LCM(1, 430) = 430
GCD(1, 430) = ( 1 x 430 ) / 430
= 1 / 430
= 1
Step3:
LCM(1, 533) = 533
GCD(1, 533) = ( 1 x 533 ) / 533
= 1 / 533
= 1
So, Greatest Common Divisor of 438, 193, 430, 533 is 1
