Given numbers are 436, 380, 521, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(436, 380) = 41420
GCD(436, 380) = ( 436 x 380 ) / 41420
= 436 / 380
= 436
Step2:
LCM(4, 521) = 2084
GCD(4, 521) = ( 4 x 521 ) / 2084
= 4 / 521
= 4
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 436, 380, 521, 257 is 1
