Given numbers are 534, 644, 243, 380
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(534, 644) = 171948
GCD(534, 644) = ( 534 x 644 ) / 171948
= 534 / 644
= 534
Step2:
LCM(2, 243) = 486
GCD(2, 243) = ( 2 x 243 ) / 486
= 2 / 243
= 2
Step3:
LCM(1, 380) = 380
GCD(1, 380) = ( 1 x 380 ) / 380
= 1 / 380
= 1
So, Greatest Common Divisor of 534, 644, 243, 380 is 1
