Given numbers are 436, 420, 985, 472
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(436, 420) = 45780
GCD(436, 420) = ( 436 x 420 ) / 45780
= 436 / 420
= 436
Step2:
LCM(4, 985) = 3940
GCD(4, 985) = ( 4 x 985 ) / 3940
= 4 / 985
= 4
Step3:
LCM(1, 472) = 472
GCD(1, 472) = ( 1 x 472 ) / 472
= 1 / 472
= 1
So, Greatest Common Divisor of 436, 420, 985, 472 is 1
