Given numbers are 436, 976, 398, 905
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(436, 976) = 106384
GCD(436, 976) = ( 436 x 976 ) / 106384
= 436 / 976
= 436
Step2:
LCM(4, 398) = 796
GCD(4, 398) = ( 4 x 398 ) / 796
= 4 / 398
= 4
Step3:
LCM(2, 905) = 1810
GCD(2, 905) = ( 2 x 905 ) / 1810
= 2 / 905
= 2
So, Greatest Common Divisor of 436, 976, 398, 905 is 1
