Given numbers are 544, 258, 688, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(544, 258) = 70176
GCD(544, 258) = ( 544 x 258 ) / 70176
= 544 / 258
= 544
Step2:
LCM(2, 688) = 688
GCD(2, 688) = ( 2 x 688 ) / 688
= 2 / 688
= 2
Step3:
LCM(2, 455) = 910
GCD(2, 455) = ( 2 x 455 ) / 910
= 2 / 455
= 2
So, Greatest Common Divisor of 544, 258, 688, 455 is 1
