Given numbers are 436, 300, 491, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(436, 300) = 32700
GCD(436, 300) = ( 436 x 300 ) / 32700
= 436 / 300
= 436
Step2:
LCM(4, 491) = 1964
GCD(4, 491) = ( 4 x 491 ) / 1964
= 4 / 491
= 4
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 436, 300, 491, 921 is 1
