Given numbers are 151, 787, 620, 408
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(151, 787) = 118837
GCD(151, 787) = ( 151 x 787 ) / 118837
= 151 / 787
= 151
Step2:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
Step3:
LCM(1, 408) = 408
GCD(1, 408) = ( 1 x 408 ) / 408
= 1 / 408
= 1
So, Greatest Common Divisor of 151, 787, 620, 408 is 1
