Given numbers are 186, 543, 508, 438
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(186, 543) = 33666
GCD(186, 543) = ( 186 x 543 ) / 33666
= 186 / 543
= 186
Step2:
LCM(3, 508) = 1524
GCD(3, 508) = ( 3 x 508 ) / 1524
= 3 / 508
= 3
Step3:
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
= 1 / 438
= 1
So, Greatest Common Divisor of 186, 543, 508, 438 is 1
