Given numbers are 670, 707, 391, 613
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(670, 707) = 473690
GCD(670, 707) = ( 670 x 707 ) / 473690
= 670 / 707
= 670
Step2:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
Step3:
LCM(1, 613) = 613
GCD(1, 613) = ( 1 x 613 ) / 613
= 1 / 613
= 1
So, Greatest Common Divisor of 670, 707, 391, 613 is 1
