Given numbers are 920, 436, 398, 957
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(920, 436) = 100280
GCD(920, 436) = ( 920 x 436 ) / 100280
= 920 / 436
= 920
Step2:
LCM(4, 398) = 796
GCD(4, 398) = ( 4 x 398 ) / 796
= 4 / 398
= 4
Step3:
LCM(2, 957) = 1914
GCD(2, 957) = ( 2 x 957 ) / 1914
= 2 / 957
= 2
So, Greatest Common Divisor of 920, 436, 398, 957 is 1
