Given numbers are 670, 286, 623, 417
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(670, 286) = 95810
GCD(670, 286) = ( 670 x 286 ) / 95810
= 670 / 286
= 670
Step2:
LCM(2, 623) = 1246
GCD(2, 623) = ( 2 x 623 ) / 1246
= 2 / 623
= 2
Step3:
LCM(1, 417) = 417
GCD(1, 417) = ( 1 x 417 ) / 417
= 1 / 417
= 1
So, Greatest Common Divisor of 670, 286, 623, 417 is 1
