Given numbers are 890, 340, 347, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(890, 340) = 30260
GCD(890, 340) = ( 890 x 340 ) / 30260
= 890 / 340
= 890
Step2:
LCM(10, 347) = 3470
GCD(10, 347) = ( 10 x 347 ) / 3470
= 10 / 347
= 10
Step3:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
So, Greatest Common Divisor of 890, 340, 347, 645 is 1
