Given numbers are 643, 580, 609, 151
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 580) = 372940
GCD(643, 580) = ( 643 x 580 ) / 372940
= 643 / 580
= 643
Step2:
LCM(1, 609) = 609
GCD(1, 609) = ( 1 x 609 ) / 609
= 1 / 609
= 1
Step3:
LCM(1, 151) = 151
GCD(1, 151) = ( 1 x 151 ) / 151
= 1 / 151
= 1
So, Greatest Common Divisor of 643, 580, 609, 151 is 1
