Given numbers are 438, 981, 213, 550
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 981) = 143226
GCD(438, 981) = ( 438 x 981 ) / 143226
= 438 / 981
= 438
Step2:
LCM(3, 213) = 213
GCD(3, 213) = ( 3 x 213 ) / 213
= 3 / 213
= 3
Step3:
LCM(3, 550) = 1650
GCD(3, 550) = ( 3 x 550 ) / 1650
= 3 / 550
= 3
So, Greatest Common Divisor of 438, 981, 213, 550 is 1
