Given numbers are 628, 226, 551, 154
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(628, 226) = 70964
GCD(628, 226) = ( 628 x 226 ) / 70964
= 628 / 226
= 628
Step2:
LCM(2, 551) = 1102
GCD(2, 551) = ( 2 x 551 ) / 1102
= 2 / 551
= 2
Step3:
LCM(1, 154) = 154
GCD(1, 154) = ( 1 x 154 ) / 154
= 1 / 154
= 1
So, Greatest Common Divisor of 628, 226, 551, 154 is 1
