Given numbers are 715, 533, 642, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(715, 533) = 29315
GCD(715, 533) = ( 715 x 533 ) / 29315
= 715 / 533
= 715
Step2:
LCM(13, 642) = 8346
GCD(13, 642) = ( 13 x 642 ) / 8346
= 13 / 642
= 13
Step3:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
So, Greatest Common Divisor of 715, 533, 642, 455 is 1
