Given numbers are 771, 145, 509, 670
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(771, 145) = 111795
GCD(771, 145) = ( 771 x 145 ) / 111795
= 771 / 145
= 771
Step2:
LCM(1, 509) = 509
GCD(1, 509) = ( 1 x 509 ) / 509
= 1 / 509
= 1
Step3:
LCM(1, 670) = 670
GCD(1, 670) = ( 1 x 670 ) / 670
= 1 / 670
= 1
So, Greatest Common Divisor of 771, 145, 509, 670 is 1
