Given numbers are 438, 848, 581, 755
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 848) = 185712
GCD(438, 848) = ( 438 x 848 ) / 185712
= 438 / 848
= 438
Step2:
LCM(2, 581) = 1162
GCD(2, 581) = ( 2 x 581 ) / 1162
= 2 / 581
= 2
Step3:
LCM(1, 755) = 755
GCD(1, 755) = ( 1 x 755 ) / 755
= 1 / 755
= 1
So, Greatest Common Divisor of 438, 848, 581, 755 is 1
