Given numbers are 398, 408, 551, 356
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 408) = 81192
GCD(398, 408) = ( 398 x 408 ) / 81192
= 398 / 408
= 398
Step2:
LCM(2, 551) = 1102
GCD(2, 551) = ( 2 x 551 ) / 1102
= 2 / 551
= 2
Step3:
LCM(1, 356) = 356
GCD(1, 356) = ( 1 x 356 ) / 356
= 1 / 356
= 1
So, Greatest Common Divisor of 398, 408, 551, 356 is 1
