Given numbers are 391, 507, 688, 506
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(391, 507) = 198237
GCD(391, 507) = ( 391 x 507 ) / 198237
= 391 / 507
= 391
Step2:
LCM(1, 688) = 688
GCD(1, 688) = ( 1 x 688 ) / 688
= 1 / 688
= 1
Step3:
LCM(1, 506) = 506
GCD(1, 506) = ( 1 x 506 ) / 506
= 1 / 506
= 1
So, Greatest Common Divisor of 391, 507, 688, 506 is 1
