Given numbers are 698, 520, 747, 428
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(698, 520) = 181480
GCD(698, 520) = ( 698 x 520 ) / 181480
= 698 / 520
= 698
Step2:
LCM(2, 747) = 1494
GCD(2, 747) = ( 2 x 747 ) / 1494
= 2 / 747
= 2
Step3:
LCM(1, 428) = 428
GCD(1, 428) = ( 1 x 428 ) / 428
= 1 / 428
= 1
So, Greatest Common Divisor of 698, 520, 747, 428 is 1
